Chapter 2 - Section 2.8 - The Derivative as a Function - 2.8 Exercises - Page 163: 17

We can see a graph of $f'(x)$ below the graph of $f(x)$ $f'(x) = e^x$

$f(x) = e^x$ We can see a graph of $f'(x)$ below the graph of $f(x)$ $f'(x) \gt 0$ for all $x$ because $f$ is an increasing function. $f'(x) = 1~$ at $~x=0$ It seems that $f'(x) = e^x$
