Question

I need help with my math

Answer 1

when x = 4, b(x) = 12

Answer 2

The given function is:

`b(x)=-2x-4`

when x = -1;

`\begin{gathered} b(x)=-2(-1)-4 \\ b(x)=2-4 \\ b(x)=-2 \end{gathered}`

when x = 0;

`\begin{gathered} b(x)=-2(0)-4 \\ b(x)=0-4 \\ b(x)=-4 \end{gathered}`

when x = 4;

`\begin{gathered} b(x)=-2(4)-4 \\ b(x)=-8-4 \\ b(x)=-12 \end{gathered}`
