First, we can find the vertex at (2.5, 0). This will give us a minimum. Now we need to find the maximum number. The domain is -12 < = X < = 8. By trying different domain numbers you get different Y, or range numbers. X = -12 gives us 27, the largest Y, range, number. So, the range is 0 less than or equal to Y less than or equal to 27, or 0 < = Y < = 27.
