If you have 3/8 of a pie that means you have three slices out of a total of 8. so the denominator tells you the total number of pieces.
has degree 3, so it takes the general form

It has a root
of multiplicity 2, which means
divides
exactly, and it has a root of
of multiplicity 1 so that
also is a factor. So

Expanding this gives


The
-intercept occurs for
, for which we have

Then



So we have

Yea Any integer can be written as a fraction! Just put that integer as the numerator of a fraction with a denominator
