Question

Evaluate the function for the indicated values. f(x) = -5x+8f(-8) isf(5) is

Answer 1

`\begin{gathered} f(-8)=48 \\ f(5)=-17 \end{gathered}`

Step-by-step explanation

to evaluate the function, replace x for the given value, so

`f(x)=-5x+8`

Step 1

a) at x=-8

replace.

`\begin{gathered} f(x)=-5x+8 \\ f(-8)=-5(-8)+8 \\ f(-8)=40+8 \\ f(-8)=48 \end{gathered}`

Step 2

b) ax x=5

replace.

`\begin{gathered} f(x)=-5x+8 \\ f(5)=-5(5)+8 \\ f(5)=-25+8 \\ f(5)=-17 \end{gathered}`
