Question

Using the function rule f(x)=x^2
What is g(x) = -2f(-2) + 3?

Answer 1

To find g(x) = -2f(-2) + 3, substitute -2 for x in the function f(x) = x^2, and then apply the given equation.

Step-by-step explanation:

The function rule tells the relationship between the input or domain and the output or range. To find g(x) = -2f(-2) + 3, we need to substitute -2 for x in the function f(x) = x^2 and then apply the given equation.

Step 1: Substitute -2 for x in f(x) = x^2:

f(-2) = (-2)^2

f(-2) = 4

Step 2: Apply g(x) = -2f(-2) + 3:

g(x) = -2(4) + 3

g(x) = -8 + 3

g(x) = -5
