Question

The functions f(x) = -4x + 4 and g(x) = 4x^2 - x are given. Find f(7) and g(-2) and simplify your answers as much as possible.

Answer 1

To find f(7), substitute 7 into the function f(x) = -4x + 4. To find g(-2), substitute -2 into the function g(x) = 4x^2 - x.

Step-by-step explanation:

To find f(7), we substitute 7 into the function f(x) = -4x + 4:

f(7) = -4(7) + 4 = -28 + 4 = -24

To find g(-2), we substitute -2 into the function g(x) = 4x^2 - x:

g(-2) = 4(-2)^2 - (-2) = 4(4) + 2 = 16 + 2 = 18
