Answer
The range is {-11, -9, -7, -5, -3}
Work Step by Step
f(x) = 2x - 7
The domain is {-2,-1,0,1,2}.
The domain gives the x value so we substitute the x into the equation f(x) = 2x - 7
x=-2
f(-2) = 2(-2) - 7
f(-2) = -11
x=-1
f(-1) = 2(-1) - 7
f(-1) = -9
x=0
f(0) = 2(0) - 7
f(0) = -7
x=1
f(1) = 2(1) - 7
f(1) = -5
x=2
f(2) = 2(2) - 7
f(2) = -3
Therefore we get the range to be {-11, -9, -7, -5, -3}
