You are at an altitude of 250 feet in a hot-air balloon. You turn the burner on high and rise at a rate of 20 feet per minute for 5 minutes. Your altitude h after you have risen for t minutes is given by the function h = 250+ 201. (a) Make a table to show the altitude as a function of the number of minutes you have traveled. (b) Graph your data points-make sure to label the units on your axes. (c) Does it make sense to connect the points on the graph? Explain. 400 Altitude # of minutes ( in feet) 350 300 1 250 1.5 200 150 3 100 4 50 1 2 4 5 6 3. 2.

7. You are at an altitude of 250 feet in a hot-air balloon. You turn the burner on high and rise at
a rate of 20 feet per minute for 5 minutes. Your altitude h after you have risen for t minutes is
given by the function h = 250 + 20t.
(a) Make a table to show the altitude as a function of the number of minutes you have
traveled.
(b) Graph your data points-make sure to label the units on your axes.
(c) Does it make sense to connect the points on the graph? Explain.

(d) After 5 minutes, you turn the burner to low. This gives just enough heat to keep the
balloon from falling but not enough to make it rise any higher. Plot a point on the graph
to show how high the balloon is after 6 minutes.
(e) Does it make sense to connect the point plotted in part (d) to the rest of the graph?
Explain.
(f) What is the domain of the function?
(g) What is the range of the function?
