Question

I don't get this question lol

Answer 1

The input in this case it x. So basically the resulting function would be:
f(x) = -1/2 x +3

So then just plug in each x input in the table, and plot the points on the x-y coordinate plane:

x     y
-4   5  
-2   4
0    3
2    2
4    1

Answer 2

Basically, the inputs are the x values on the table. Plug those into the function. "Multiply the input by -1/2, then add 3" translates to -1/2(x) + 3.

If you would like me to actually put the answers down, then I'll put them in the comments after you request them.
