If $f(x)$ and $g(x)$ are two probability density functions, $f(x) = \begin{cases} \frac{x}{a}+1 & :a \leq x < 0 \\ \frac{x}{a}+1 & : 0 \leq x \leq a \\ 0 & :\text{otherwise} \end{cases}$ ... different; Variance of $f(x)$ and $g(x)$ are same Mean of $f(x)$ and $g(x)$ are different; Variance of $f(x)$ and $g(x)$ are different
