# Homework Help: Gaussian curve, x is a log scale

Hello!
If I have the gaussian function, but x is a loarithmic scale. Can I infer that, if x was plotted using a regualr scale, that the function would be 'fairly' linear? At least initially? As the rate of change gradually increases befor slowing down again. I think this is reasonable... I don't know how to try and represent it mathematically.

The Gaussian curve is
$$y= ae^{-x^2}$$
so if x is a log scale you have
[tex]y= ae^{-(log x)^2}[/itex]
No, that is not a linear function.
