Lesson 5 The Tortoise and the Hare Solidify Understanding
Identify which of the following representations are functions. If the representation is NOT a function, state how you would fix it to make it a function.
The number of calories you have burned since midnight at any time during the day.
The graph in Figure 1 shows time (minutes) on the
Which car has the cruise control on (is maintaining at the same speed)? How do you know?
Which car is accelerating? How do you know?
Identify the interval in Figure 1 where car A has gone farther than car B.
The graph of the speed of a third car, Car C, which has an exponential relationship is now shown in the graph (see Figure 2). All 3 cars have the same destination.
If the destination corresponds with a distance of
If the three cars passed the starting point at the same time, and were racing, would there ever be another time that they would be tied? Explain.
Describe the race for these three cars.
If the cars are able to proceed beyond a time of
On a graph that shows distance versus time, what do you look at in order to find speed?
State the domain and range of each graph. Use interval notation where appropriate.
Are the domains of #19 and #20 the same? Explain.
