Describe a relationship modeled by the function f(x) = 4x3 − 72x2 + 320x

Explanation:

To find a relationship modeled by the given function it is recommendable to factor it.

The function is:

The first step to factor it is to extract common factor 4x:

The second step is to factor the quadratic trinomial.

That is made by writting it as a product of two binomials, for which the two constant terms add up - 18 and their product is 80. Those terms are -10 and - 8; so the two factors are (x - 10) and (x - 8), and the factored form is:

Then, a relationship modeled by that polynomial is the volume of right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.

Thus, the volume of the prism is the product of the three factors:
