Question

The following table lists the calories burned by a 120-pound person strolling.

time(minutes) 10 30 50 80
Calories 20 60 100 160

(a) Do you think the point (0,0) could be added to this table? Why or why not?


(b) What kind of function would model this data?


(c) Find a function C(t) that models the calories burned in t minutes.

Answer 1

c(t) = 2t

Answer 2

yes, 0,0 is a point on that graph, however, the graph doesn't exist for negative values of t, since time cannot be negative. so c(t) = 2t, fot t>=0

Answer 3

spelling mistake, it should have been for t >= 0

Answer 4

b) a linear function would model this data.
