Orca J-43 is sighted in Pudget Sound at the following depths (in feet) at certain times t (in minutes) measured from sea level. D(t) = 59 0 ≤ t < 5 t 2 − 22t + 144 5 ≤ t < 10 24 10 ≤ t < 18 8(t − 15) 18 ≤ t ≤ 22 (a) What is the range of the function D? Strategy then final result, no algebra steps (b) Another orca, K-97, also shows her presence in Pudget sound. If her depths (measured at the same time as above) is given by g(t) = 2t + 1, at which times are both whales at the same depth? Strategy then final result, no algebra steps
