Question

F(x) = x +4 and g(x) = 12x -6 what is f(3) + g (-1)

Answer 1

Answer:

(C) -11

Step-by-step explanation:

The given functions are;

$f(x)=x+4$

Plug in x=3.

This implies that; $f(3)=3+4=7$

and

$g(x)=12x-6$

Plug in x=-1

This implies that; $g(-1)=12(-1)-6=-18$

$f(3)+g(-1)=7+-18=-11$
