Question

Evaluate the function when x= -2,0, and 59) v(x)=12-2x-5

Answer 1

we have the function

`V(x)=12-2x-5`

Combine like terms and rewrite the given function

`V(x)=7-2x`

Evaluate for x=-2

`\begin{gathered} V(-2)=7-2(-2) \\ V(-2)=7+4 \\ V(-2)=11 \end{gathered}`

Evaluate for x=0

`\begin{gathered} V(0)=7-2(0) \\ V(0)=7 \end{gathered}`

Evaluate for x=5

`\begin{gathered} V(5)=7-2(5) \\ V(5)=7-10 \\ V(5)=-3 \end{gathered}`
