To find the range, plugin the domain number where the x is located and solve for f(x)

D= {-4, -2, 0, 2}
f(x) = 4x +9

f(-4) = 4(-4) + 9 = -7
f(-2) = 4(-2) + 9 = 1
f(0) = 4(0) + 9 = 9
f(2) = 4(2) + 9 = 17

With the given domain, the range of the function is [-7, 17]. That is -7 to 17.

The range of the function without the given range is (- infinity, infinity).
