Question

Practical Domain and RangeLet the function M(t) 12t represent the distance in miles that you would travel bicycling t hours.Assume you can bike no more than 13 hours. Find the practical domain and practical range for M(t).All answers must include correct units of measure.Practical Domain:

Answer 1

From the problem, we have the function :

$M(t)=12t$

You can bike no more than 13 hours so the time will range from 0 to 13 hours.

The domain of t will be :

$0\le t\le13$

The range of M(t) will be the values when substitute the domain of t.

That will be :

$\begin{gathered} M(0)=12(0)=0 \\ M(13)=12(13)=156 \end{gathered}$$0\le M(t)\le156$
