Question

PLEASE I NEED HELP!!! IT"S FOR MATH< IT"S ABOUR EVALUATING FUNCTIONS

Answer 1

Answer:

a) f(3) = -19

b) x = -2 (I assume you have to find x, but the question isn't very clear)

Step-by-step explanation:

a) f(3) = -4(3) - 7 = -12 - 7 = -19

b) Suppose f(x) = 1. Then 1 = -4x - 7, so -4x = 8, and thus x = -2
