What is a function?
Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The graphs of the function
Now,
we can identify which exponential function is represented by the graph:
The graph crosses the y-axis at (0, 2), so the y-intercept is 2. This means that a = 2.
The graph is increasing as x increases, so b > 1. We can find b by using another point on the graph, such as (1, 6). We can substitute these values into the formula and solve for b:
f(1) = 2b^1
6 = 2b
b = 3
Therefore, the exponential function will be f(x) = 2(3)^x.

Answer:
$357.42
Step-by-step explanation:
So first I multiplied $425.50 by 20%.
$425.50 * 0.20= 85.10
$425.50- 85.10= $340.40
$340.40 * 0.05 = $17.02
$340.40 * 0.07 = $23.828
$340.40 + 23.828 + 17.02= $ 357.42

Select the correct answer. A triangle has vertices (-1, 2), (3, 1), and (7, 2). What is the approximate perimeter of th...
Answer:
16.24 Units
Step-by-step explanation:
The perimeter of the triangle is the sum of the length of the sides of the triangle. Given the points on the vertices, the length of each side may be found using the formula
Length = √(x2 - x1)^2 + (y2 - y1)^2
Considering the pair (-1, 2), (3, 1), the length of that side
= √(3 -- 1)^2 + (1-2)^2)
= √(16 + 1)
= √17 units
Considering the pair (-1, 2), (7, 2), the length of that side
= √(7 -- 1)^2 + (2-2)^2)
= √(64)
= 8
Considering the pair (3, 1), and (7, 2), the length of that side
= √(7 - 3)^2 + (2 - 1)^2
= √(16 + 1)
= √17
Hence the perimeter of the triangle
= √17 + 8 + √17
= 4.12 + 8 + 4.12
= 16.24 Units

Find the greatest common factor of the following monomials:
12x^3 6x^4 18x^2
Answer:
6
Step-by-step explanation:
first, look at the first two coefficents, (12,6) 6 can divide 12 and 6 obviously didvides itself so we can day the gcd(12,6) is 6. now look at the last two coefficents (6,18). Similarly we can see that the gcd here is also 6.
finally, look at 12 and 18, neither divide each other so we can try dividing them by our most common gcd so far 6. this yields 2,3. niehter can be simplified further so we can conlcude the gcd of this monomials is 6
please help asap I will give you 15 points. no links or ill report you
Answer:
Step-by-step explanation:
Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is
R = (-∞, 3] or another way to state this is
R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".

(0, ), (-1,), (1, ) y=2x+1
Help
Answer:
(0, 1)
(-1, -1)
(1,3)
Step-by-step explanation:
Given the function;
y = 2x + 1
when x = 0
y = 2(0)+1
y = 1
Hence the required pair is (0, 1)
when x = -1
y = 2(-1) + 1
y = -2 + 1
y = -1
Hence the coordinate is (-1, -1)
when x = 1
y = 2(1) + 1
y = 2 + 1
y =3
Hence the coordinate is (1, 3)

Please can someone give me a good step to step guide on how to get this one.
Thank you!
Answer:
Step-by-step explanation:
First of all notice that slope has a negative value
Also notice that line cuts the y axis in -1
because of the symetry of the line you can deduce that the slope is -1, also you can calculate it using the fact that the points (-1, 0) and (0, -1) belongs to the line, the slope would be:
m=(0-(-1))/(-1-0)=-1
finally the equation is
y=-x-1
What is the value of x in the below diagram?
(2 x + 2)
(x + 34)°
Answer:
Step-by-step explanation:
x+34+2x+2=180 degree (being liear pair)
3x+36=180
3x=180-36
x=144/3
x=48
Answer:
x + 34° + 2x + 2° = 180°
3x = 180° - 34° - 2°
3x = 144°|: 3
x = 48°
x + 34° = 82° and 2x + 2° = 50°

If f(1) =4 and f(n) = -4f(n-1) + n then find the value of f(5)
======================================================
Work Shown:
We use the first term to build to the second term.
Plug in n = 2
f(n) = -4f(n-1) + n
f(2) = -4f(2-1) + 2 ..... n replaced with 2
f(2) = -4f(1) + 2
f(2) = -4*4 + 2 ......... f(1) replaced with 4; since f(1) = 4
f(2) = -16 + 2
f(2) = -14
The second term is -14
------------------
Repeat for n = 3
f(n) = -4f(n-1) + n
f(3) = -4f(3-1) + 3 ..... n replaced with 3
f(3) = -4f(2) + 3
f(3) = -4*(-14) + 3 ......... f(2) replaced with -14
f(3) = 56 + 3
f(3) = 59
The third term is 59
------------------
We keep going until we get to f(5)
Plug in n = 4
f(n) = -4f(n-1) + n
f(4) = -4f(4-1) + 4 ..... n replaced with 4
f(4) = -4f(3) + 4
f(4) = -4*(59) + 4 ......... f(3) replaced with 59
f(4) = -236 + 4
f(4) = -232
The fourth term is -232
------------------
Just one more section
Plug in n = 5
f(n) = -4f(n-1) + n
f(5) = -4f(5-1) + 5 ..... n replaced with 4
f(5) = -4f(4) + 5
f(5) = -4*(-232) + 5 ......... f(4) replaced with -232
f(5) = 928 + 5
f(5) = 933
The fifth term is 933
------------------
As you can see, recursive sequences can get tedious for fairly large values of n. We need to compute every term before f(5) to figure it out. So if your teacher needed you to compute something like f(10), then it would get even worse. Sometimes it's possible to find a closed formula for it, but it may be tricky to find.
Myra wrote a computer program that had 75 lines of code. She realized that she could make the code more efficient and removed 20% of the lines.
Shade the grid to show the percent that Myra removed.
Answer:
Now Myra has 60 lines of code, no grid picture attached.
Step-by-step explanation:
If Myra removed 20% of the lines and she started with 75 lines of code, then she is removing 1/5 of those lines of code.
75 divided by 5 is 15, and 75 - 15 = 60
Now Myra would have 60 lines of code. It's unclear what grid you are talking about though - could you attach a picture of the grid you need to shade in?
