Range={12, -10, 2}
Range={-12, -10, -2}
None of the above

Answer 1

just replace the three values you are given for x (you domain) in order to compute the corresponding values for y, what you get will be the range for the function you're given

Answer 2

-9

Answer 3

and none of the above have -9 so its none of the above.. am i correct ?

Answer 4

you have three values for x: -1, 0 and 4
