Question

How da heck do I do this

Answer 1

{6,9,16,18}

Explanation:

We are given:

y=x+9 where x is in {-3,0,7,9}.

The range is a list of y-elements that correspond to that list of x-elements.

So we plug in the values to get our list for the range.

Add 9 to each since it says to find y you add 9 to your x.

y is in {-3+9,0+9,7+9,9+9}.

Let's simplify:

y is in {6,9,16,18}.
