1. You drive to school, going slow at first, and then speeding up so you won’t miss Calculus.
But you slow down when you see a police car, and speed up again. But right before you
get to school you realize that you desperately need an espresso, so you drive to the local
cafe and get one to go. Then you rush to school and the fun at Calculus. Sketch a graph
of your distance traveled as a function of time. Label the different sections of the graph
explaining what is going on.
2. Find the formula of the linear function in slope intercept form whose input is tem-
perature in Fahrenheit and whose output is what the temperature is in Celsius. Use the

Fahrenheit corresponds to 100 degrees in Celsius .
