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

-9

anonymous · Answer

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

helder_edwin · Answer

you have three values for x: -1, 0 and 4
none of them gives you y=-9

anonymous · Answer

i plugged - 1 in to x and solved and got -9
