Step-by-step explanation:
Look at the picture.
The function has a realtive maximum of -1 at x = 0.
The function has a realtive minimum of -6 at x = 5.
The function is increasing on the intervals: (-∞, 0> and <5, ∞).
The function is decreasing on the interval: <0, 5>.
The domain of the function is: (-∞, ∞) = R
The range of the function is: (-∞, ∞) = R
