The volume, in cubic centimeters, of a fish
tank is represented by the polynomial
model

The polynomial's maximum value is relative.
Here we have the polynomial:
[tex]V(x) = 36x^2 - 3.75x^3[/tex]
Notice that the leading coefficient is negative, so, as x tends to negative infinite, V(x) will tend to positive infinite.
So we only have a relative maximum, because is local maximum (at x = 6.4), but the function can take larger values than that.
You can also check that on the graph of V(x), which you can see below:
