You need to find the equation of product function such that:

`f(x)*g(x) = sqrt x*x^2`

Notice that the equation of the function contains the square root function, hence you need to impose that radicand to be positive such that:


Hence, the domain of the function is the interval `[0,oo)`  and the range is also the interval `[0,oo).`
