What is the range of the function y=2x-3 when the domain is {-1,0,5}

Domain = x
range = y

when the domain is -1
y = 2(-1) - 3
y = -2 - 3
y = -5
range is -5

When the domain is 0
y = 2(0) - 3
y = 0 - 3
y = -3
range is -3

when the domain is 5
y = 2(5) - 3
y = 10 - 3
y = 7
range is 7

The range is { -5, -3, 7 }

hope this helps
