Question 169526
Substitute each element of your domain set into the function to find the corresponding element of the range.  The range is the y value.  The x is called the domain.

I'll do one and you can follow my notes and do the rest.

From the elements given, I will pick -2.

So, let x = -2 in the function and simplify.

y = 2 + x/4....This is your function.

y = 2 + -2/4

y = 2 + -1/2

y = 3/2

Can you take it from here?
