Question

F(x) =5x-8 when x=-3,0, and 4z

Answer 1

Answer:

$- 23 = f(-3) \\ - 8 = f(0) \\ 12 = f(4)$

Step-by-step explanation:

$5(4) - 8 = 20 - 8 = 12 \\ 5(0) - 8 = 0 - 8 = - 8 \\ 5( - 3) - 8 = - 15 - 8 = - 23$

Answer 2

Answer:

f(3)= 5(3)-8= 15-8= 7

f(0)= 5(0)-8= 0-8= -8

f(4z)= 5(4z) - 8 = 20z - 8
