Question

I got -6, -5, -4, and -3 as my answers when I was trying to solve for y to complete a function table when the rule is 1/2x+(-4).Did I get the right answers?

Answer 1

Rule:

$\frac{1}{2}x+(-4)$

x= -4

$\begin{gathered} y=\frac{1}{2}(-4)+(-4) \\ \\ y=-\frac{4}{2}-4 \\ \\ y=-2-4 \\ \\ y=-6 \end{gathered}$

x= -2

$\begin{gathered} y=\frac{1}{2}(-2)+(-4) \\ \\ y=-\frac{2}{2}-4 \\ \\ y=-1-4 \\ \\ y=-5 \end{gathered}$

x=0

$\begin{gathered} y=\frac{1}{2}(0)+(-4) \\ \\ y=0-4 \\ \\ y=-4 \end{gathered}$

x=2

$\begin{gathered} y=\frac{1}{2}(2)+(-4) \\ \\ y=\frac{2}{2}-4 \\ \\ y=1-4 \\ \\ y=-3 \end{gathered}$
