An icicle drips at a rate that can be represented by the function f (x) = - x2 + 9x - 18, where 0 ≤ x ≤ 10 and x is the number of hours after the sun has risen. When f (x) is a negative number, the icicle is not dripping. Determine the values when the icicle starts and stops dripping.

x = - 3 and x = 6

x = 3 and x = - 6

x = 3 and x = 6

x = - 3 and x = - 6
