Question

if f(x) = x3 and g(x) = 2x + 7, what is g(x)
when x = -4?

Answer 1

Answer:

G(x) when x= -4 is 1.

Step-by-step explanation:

$g(x)=2x+7\\\\[when x= -4, g(x) becomes: \\\\g(-4)= 2(-4) +7\\\\Do PEMDAS with your current equation, multiplying the -4 by the two outside the parenthesis.\\\\g(-4)= -8 + 7\\\\add.\\\\g(-4)= 1$
