Question 250253: Please help me help my daughter solve this homework problem.
For a car traveling at a constant rate of 60 mi/h, the distance traveled is a function of the time traveled.
a. Express this relation as a function
b Find the range of the function when the domain is [1,5,10]
c What do the domain and range represent?
I am thinking that the expressed function should be something like
f(d) = (60m)h
We can solve b. once we can figure out how to express it as a function.
Thank you for your help.
