4 0

It is true because a rational function is defined as those functions where the variable is placed in the denominator, which must be restricted, because all denominators cannot be equal to zero, other wise it would be undetermined

Write a real world problem that could be modeled by a linear function whose x-intercept is 5 and y-intercept is 60.

The y-intercept is 60 so say you start with 60 apples. And the x-intercept is 5 so lets say you eat them all in 5 days. So the equation would look somthing like this $Y=-12x+60$ and would end up having a word problem that says somthing like "Jimmy has 60 apples and eats 12 a day how many days go by before Jonny has no more apples ?"
