Which functions are symmetric about the y-axis? Check all of the boxes that apply.
The functions that are symmetric about the y-axis are;
1) The function in the first option; f(θ) = cos(θ)
2) The function in the third option; f(x) = x²
Reason for the above selection;
Definition;
A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x
Analysis of the graphs;
First Function Graph; The graph represents the graph of cos (θ)
∴ The function is f(θ) = cos(θ)
The value of the function when x = π, f(π) = -1
Similarly, the value of the when x = -π, f(-π) = -1
f(π) = f(-π)
∴ f(x) = f(-x)
Therefore; the first function is an even function
Second Function Graph; The function of the graph is x = y²
∴ y = √(x)
The value of the function when x = 4, y = f(4) = 2
However, the when x = -4, f(-4) does not exist
f(4) ≠ f(-4)
∴ f(x) ≠ f(-x)
Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)
Third Function Graph; The function the graph represents is y = x²
The value of the function when x = 2, f(2) = 4
Similarly, the value of the when x = -2, f(-2) = 4
f(2) = f(-2)
∴ f(x) = f(-x)
Therefore; the third function is an even function
From the above, the functions which are symmetric about the y-axis, (even functions) are;
The first and the third functions

Consider the function f(x) = (x+ 1)2 - 1. Which of the following functions stretches
fo) vertically by a factor of 4?
O A) f0 - (/ax+ 1)2 +3
O B) f9 = 1/ax+ 1)2 -4
Oo fo-4(x+ 1)2 - 1
OD) fo = 4(4x+ 1)2- 1
Answer:
C
Step-by-step explanation:
A coefficient of 4 would have to be added in front of (x+1)^2 in order to vertically stretch the function by a factor of 4.
The answer that demonstrates this is choice C: [tex]f(x) = 4(x+1)^2-1[/tex]
The functions stretches vertically by a factor of 4 will be f(x) = 4(x+ 1)² - 1. Then the correct option is C.
What is the equation of the parabola?Let the point (h, k) is the vertex of the parabola and a is the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic function is given below.
f(x) = a(x+ 1)² - 1
If the value of the leading coefficient lies between 0 to 1. Then the parabola is stretched horizontally.
And if the value of the leading coefficient is greater than one. Then the parabola is stretched vertically.
The functions stretches vertically by a factor of 4. Then the value of the leading coefficient is 4. Then the equation will be
f(x) = 4(x+ 1)² - 1
Then the correct option is C.

The variables x and y very directly. Use the values to find the constant of proportionality K then write equation that relates to x and y. Write any fraction in simplest form. Y equals 20 and X equals 12
Answer:
k=5/3
Step-by-step explanation:
The variables x and y vary directly. Given that, y = 20 and x = 12
We can write it as :
y=kx
Where k is constant of proportionality
Put the values of x and y
20=12k
k = 20/12
k = 5/3
So, the value of the constant of proportionality is 5/3.

domain represents the numbers at the x endpoints of a graph.
on the graph we see that on the left, the line ends when x is -4
on the right, the line ends when x is 4
the domain is
-4, 4
but notice how on the left there is an open circle
this will be written with a parentheses
( -4, 4
and notice how on the right there is a closed circle
this will be written with a bracket
