All polynomials are rational functions, that perhaps I should just imagine them as "over 1". Good. But the definition of a rational function has the concept of "ratio" in it. And when I found this:
A cylinder has a volume of $\left(x+3\right)\left({x}^{2}-3x-18\right)\pi$ cubic centimeters. Find the height of the cylinder.
I wondered how this is a ratio of any sort?(It can't be a ratio of the expression over 1) So if $a=\left(x+3\right),b=\left({x}^{2}-3x-18\right)$, and $c=\pi$,
can we say a,b,c are "in a ratio," i.e., a:b:c?
