I need help solving and graphing this problem

[lainy74]

I have to solve this problem and I am not sure how I am suppose to solve it

Many different kinds of data can be modeled using polynomial functions. An example of a polynomial function would be gas mileage for an automobile. If we compare gas mileage at two different speeds, V1 and V2, the gas required varies as (V1/V2), raised to the third power, (V1/V2)3.

Rational functions are also useful. For example, a cubic/cubic model can be used to explain the thermal expansion of metals with temperature. Rational functions have been used to describe problems as diverse as the movement of blood through the body to how to produce items at the lowest possible cost.

Can anyone help me with this problem
Thank you in advance

Okay.... You've posted your book's discussion of how rational functions can be useful. But what's your question? There is no actual exercise here...?
