Question

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

Answer 1

f(x)=3x-1

Evaluate the function in x=-2

`\begin{gathered} f(-2)=3\cdot(-2)-1 \\ f(-2)=-6-1 \\ f(-2)=-7 \end{gathered}`

g(x)=-x+6

Evaluate the function in x=5

`\begin{gathered} g(5)=-5+6 \\ g(5)=1 \end{gathered}`

Add these values

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

The answer is -6
