I have two graphs **f(x)** and **g(x)** which exist on the same infinite domain. I want to create a graph **h(x)** that plots **f(x) * g(x)** against **x1 * x2** and I'm not sure how.

To be precise, I want to take two univariate Gaussian distributions and graph them as one distribution where $\mu$ is equal to or close (rightward skewed) to $\mu_1 + \mu_2$.
