My Math Forum Is this pdf bounded?

The question asks to find the constant $\displaystyle c$ so that $\displaystyle f(x)$ is a pdf of a random variable $\displaystyle X$. Then asks is this pdf bounded? I cannot find in my notes or text how to find if a pdf is bounded. To solve for $\displaystyle c$ $\displaystyle f(x) =c/\sqrt{x}$ , \$\displaystyle 0
