Determine the range of the function f(x)=3x-9 when the domain is {-2, 0, 3}. {-6, 0, 9} {-15, -9, 0} {3, 9, 18} {-2, 0, 3}

It is the second one. all u do is substitute -2, 0, and 3 (one at a time of course) and then u should end up with three numbers after u solve each equation. so

3 x -2 -9= -15
etc.

hope this helps
brainliest?

W-14=t. that i think is the answer idk
