The toll T charged for driving on a certain stretch of a toll road is $4 except during rush hours (between 7 AM and 10 AM and between 4 PM and 7 PM) when the toll is $6. (a) Sketch a graph of T as a function of the time t, measured in hours past midnight. T T O t= O T 6 7 10 7 10 16 19 16 19 24 Classify the discontinuities as removable, jump, or infinite.

O Because of the sudden jumps in the toll, drivers may want to avoid the higher rates between t = 7 and t = 10 and between t = 16 and t = 19 if feasible. O Because of the sudden jumps in the toll, drivers may want to avoid the higher rates between t= 0 and t = 7, between t= 10 and t = 16, and between t= 19 and t = 24 if feasible. O Because of the steady increases and decreases in the toll, drivers may want to avoid the highest rates at t = 7 and t = 24 if feasible.
