# Draw e^ax

My nephew gets confused in drawing exponential curves with many variations: $\boxed {y = e^{ax} }$

If $-e^{ax}$, then reverse the y values, that is flip the curve over x-axis.

Math Joke:

Note:

$\frac {dy}{dx} e^{x} = e^{x}$
$\int e^{x} dx = e^{x} + c$

Mathematically, this is $e^{x} \text { increases much faster than x increases}$
$\frac{d}{dx} e^{x} = e^{x}$
