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

Mathew Effect of e^x

“For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken even that which he hath.”

—Matthew 25:29, King James Version

Or, “the rich gets richer, the poor gets poorer.”

Mathematically, this is e^{x} \text { increases much faster than x increases}

\frac{d}{dx} e^{x} = e^{x}
