Answer:
{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}.
