Find f(-2) for the function f(x)= 3x2-2x+7

4vir4ik [10]

Answer:

f( - 2) = 23

Step-by-step explanation:

$f(x) = 3 {x}^{2} - 2x + 7 \\ plug \: x = - 2 \\ f( - 2) = 3 {( - 2)}^{2} - 2( - 2)+ 7 \\ = 3 \times 4 + 4 + 7 \\ = 12 + 11 \\ \huge \red{ \boxed{ f( - 2) = 23}}$

Function and Reasoning:

The number of calories per ounce of soda is 10

<h3>Part A: Represent the relationship between the number of calories and the number of ounces</h3>

The given parameters are:

Calories = 50

Ounces = 5

Let the number of calories be y and the ounces be x.

So, we have:

y = kx

Substitute y = 50 and x = 5

50 = 5k

Divide by 5

k = 10

Substitute k = 10 in y = kx

y = 10x

See attachment for the graph of the relationship between the number of calories and the number of ounces

<h3>Part B: What is the number of calories per ounce of soda?</h3>

In (a), we have:

k = 10

This means that the number of calories per ounce of soda is 10

<h3>Part C: How does the unit rate relate to the slope of the line in the graph above? </h3>

The unit rate and the slope represent the same and they have the same value
