Is {-6, -2, 0} supposed to represent a given domain?
5. f(x) = -2x + 1; {-6, -2, 0}
f(-6) = 12+1 =13
f(-2) = 4+1 = 5
f(0) =1
Range {1,5,13}
6. f(x) = x3 + 1; {-2, -1, 3}
f(-2) = (-2)^3+1 =-7
f(-1) = (-1)^2 +1 =0
f(3) = (3)^3 +1 = 28
Range = {-7,0,28}
f(-6) = 12+1 =13
f(-2) = 4+1 = 5
f(0) =1
Range {1,5,13}
6. f(x) = x3 + 1; {-2, -1, 3}
f(-2) = (-2)^3+1 =-7
f(-1) = (-1)^2 +1 =0
