Question

Give the range of x - 2y = 0 for the domain {-1, 0, 4}. Help please? I don't understand what it wants me to do.

A.Range = {-2, 0, 8}
B.Range = {-1, 0, 4}
C.Range = {5, 0, -2}
D.Range = {-1/2, 0, 2}

Answer 1

Plug in -1 and get y = -1/2 Since D is the only choice that contains -1/2, choose D

Answer 2

Thanks!!!
