For the Function g(x)=x^5-9x^3 solve the following for g(x)>0

step by step solution:

The given function is:

g(x)=x^{5}-9x^{3}

We want to solve for

 g(x)\gt0

on Substituting the value of the given function into the inequality we get

\textcolor{primary}{x^{5}-9x^{3}}\gt0

Solve the inequality for x:

x^3(x^2-9)>0

x^3(x-3)(x+3)>0

now we can conclude that the solution of x will be :

x\in(-3,0)\cup(3,\infty)
