Find the solution for y=4-2x, given the domain of { - 2,-1,1,3,4 }

Y = 4-2x

-2 ... y = 4 - 2 (-2) = 4 - - 4=4+4 = 8

-1 ... y = 4 - 2 (-1) = 4 - - 2=4+2 = 6

1 ... y = 4 - 2 (1) = 4 - 2 = 2

3 ... y = 4 - 2 (3) = 4 - 6 = - 2

4 ... y = 4 - 2 (4) = 4 - 8 = - 4

{8, 6, 2, - 2, - 4}

{-4, - 2, 2, 6, 8}
