Question

Given f(x) = 3x - 1 and g(x)= -x + 6, find f(-2) + g(5). A. -6 B. 6 C. 8

Answer 1

Answer:

A. -6

Step-by-step explanation:

$f(x)=3x-1$

In order to find $f(-2)$ we will plugin $x=-2$

$f(-2) = 3(-2)-1\\f(-2)=(3\times(-2))-1\\f(-2)=-6-1$

$f(-2)=-7$

$g(x)=-x+6$

In order to find $g(5)$ we will plugin $x=5$

$g(5)=-5+6$

$g(5)=1$

$f(-2)+g(5)\\=-7+1\\=-6$

∴ $f(-2)+g(5)=-6$
