Solution:

Hi there! What we need to do is plug in the value of x into the function:

[tex]\stackrel\diamondsuit{\boxed{\boxed{\begin{aligned} \textsf{If x=-1}\\\sf{y=5(-1)}\\\sf{y=-5} \end{aligned}~~~~~~~~~~\begin{aligned}\textsf{If x=0} \\\sf{y=5(0)}\\\sf{y=0} \end{aligned}~~~~~~~~~~~~~\begin{aligned}\textsf{If x=1}\\\sf{y=5(1)}\\\sf{y=5}\\\end{aligned}}}}[/tex]

So, we end up with the following table:

[tex]\stackrel\diamondsuit{\boxed{\boxed{\begin{tabular}{c|1}\sf{If x= & \sf{then y}= \\\cline{1-2} \\-1 & -5\\0 & 0\\1 & 5\end{tabular}}}}}[/tex]

I hope this helps! ^^
