This is just a fancy way your teacher saying that when you have an equation y=
+1, what is y when x=-1,0,3.
We just need to solve by substituting the x in respectively.
x=-1, y=
![(5)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/a5g1oaa42du8woizda4ioja3y0bqpgvuhh.png)
x=0, y=1
x=3, y=65
Hope this helped! Any questions just put it in the comments.
