Question

For each of the following functions, evaluate: f(-4), f(-2), f(0), f(2), and f(4)
17.)f(x)=3x-7
19.) ƒ(x)=−2x²+5x+1

Answer 1

Answer for 17. f(-4)= -19 , f(-2) = -13 , f(0)= -7 , f(2) =-1 , f(4) =5
Answer for 19. f(-4)= -51 , f(-2) = -17 , f(0)= 1 , f(2) =3 , f(4) =-11

Replace the x with the given number for example. It's just like solving for x in equations.
f(x)=3x-7
f(-4)=3(-4)-7
= -12 - 7
= -19
