Domain and range word problems

Question

Let the function M(t)=15t represent the distance you would travel bicycliingt hours. Assume you can bike no

more than 10 hours. Find the practical domain for this function. Write the answer in words,

Answer 1

In this problem, t, the hours of bicycling represents the domain.

As it is stated in the problem, "Assume you can bike no more than 10 hours," the hours of bicycling cannot exceed 10.

Also, it is NOT possible to have negative hours. You cannot ride a bicycle for negative hours.

Therefore, t has to be larger of equal to 0 and less than or equal to 10.

0 ≤ t ≤ 10
