Which Relation Is Also A Function?

Answers

Answer 1

Answer:

D.

Step-by-step explanation:

The easiest way to tell is a relation is a function is to look at every x. A function cannot have two x's that are the same.

A. There are two x's with the value of 10.

B. There are two x's with the value of 20.

C. If you wrote this in ordered pairs, there would be two x's with the value 2.

D. Every x is different, so the answer is D.

For some reason, in our history class, there are 14 more boys than there are girls. If a total 32 students are in the class, how many boys and how many girls are there

Answers

Answer:

We can assume X is the number of girl, so the number of boy should be X+6.

 

Based on question, we can get X+X+6=32

2X+6=32

2X=26

X=13

So the answer is, 13 girls are in the class.

If the function f(x)= 2x – 3 and g(x) = 3/2x + 1 then which of the following is a true statement?

f(0) > g(0)
f(8) = g(8)
f(2) = g(2)
g(4) < f(4)

Answers

Answer:

f(8) = g(8)

Step-by-step explanation:

Given

f(x)= 2x – 3 and g(x) = 3/2x + 1

f(0)= 2(0)-3

f(0) = -3

g(0) = 3/2(0)+1

g(0) = 0+1

g(0) = 1

Hence since -3 < 1, this means that f(0)<g(0)

Also;

f(8)= 2(8)-3

f(8) = 16-3

f(8) = 13

g(8) = 3/2(8)+1

g(8) =12+1

g(8) = 13

This shows that g(8) = g(8)

Hence g(8) = g(8)  is a true statement

Which statements correctly describe the graph of the function f(x) = x3 – 4x2 – 3x + 18? Select three options.

There are three unique solutions to the function when y=0.

The function has a double root.

As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.

As x approaches negative infinity, y approaches positive infinity.

The domain and range of the function are the set of real numbers.

Answers

Answer:

(B) The function has a domain of all real numbers.

(C) The function has a range of {y|–Infinity < y < Infinity}.

(E) The function passes through the point (3, –27).

Step-by-step explanation:

The statements are true.

What is faction?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

The given function is:

f(x) = x³- 4x² - 3x + 18

After plotting its graph can see the graph of the function.

The statements that are true are:

As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.

You can see this in the graph and may be really hard to see it without the graph, the easier way would be to see the derivate of f(x) and see that is first positive, then negative, and then positive.

f'(x) = 3x² - 8x - 3

As the leading coefficient is positive, the arms open up, and f'(0) = -3

Then is easy to see that from left to right, is positive, then negative, and then positive again.

The domain and range of the function are the set of real numbers.

For the domain, we do not have any denominator nor weird function that has problems in a particular value, so the domain is the set of all real numbers.

And as you can see, as the leading coefficient is an odd power of x, the range will go from minus infinity to infinity (you can also see it in the graph).

The function has a double root.

Yes, in the graph you can see two roots, but this is a 3rd-degree polynomial, so it must have 3 roots, this means that one of the roots in the graph is a double root. (Where the double root is at x = 3, as you can see in the graph)

4. A recipe for orange water says, "Mix 3 teaspoons yellow water with 1 teaspoon red water." For this recipe, we might say: "The ratio of teaspoons of yellow water to teaspoons of red water is 3 : 1." Write a ratio for 2 batches of this recipe. Write a ratio for 4 batches of this recipe.

Answers

Answer:

2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water

4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water

Step-by-step explanation:

1 batch

Yellow water = 3 teaspoons

Red water = 1 teaspoons

Yellow water : Red water = 3 : 1

2 batches of orange water

Multiply the ratios by 2

Yellow water : Red water

= (3 : 1) * 2

= 6 : 2

2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water

4 batches of orange water

Multiply the ratios by 4

Yellow water : Red water

= (3 : 1) * 4

= 12 : 4

4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water

Answer:

2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water

4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water

Step-by-step explanation:

1 batch

Yellow water = 3 teaspoons

Red water = 1 teaspoons

Yellow water : Red water = 3 : 1

2 batches of orange water
