Q. Janice is working as a babysitter for the Harold Family.  They plan to leave for their date at 7:00 pm  and be back by 12:00 am.  If the equation f(x) = 15x + 20 models the amount that Janice will earn, where x is the number of hours she works, and f(x) is the total money she earns, what is an appropriate domain?

• Question 6
120 seconds
Q. The lake has a depth of 45 feet below sea level.  A scuba diver is taking a dive.  His depth under water  can be modeled by
