### What is the slope of the exponential function f(x)?

The exponential function f(x)=ex has at every number x the same “slope” as the value of f(x). That makes it a very important function for calculus. For example, at x =0,theslopeoff(x)=ex is f(0) = e0 =1. That means when you ﬁrst drove o↵ the lot (x =0)theodometerread1mile,and your speed was 1 mile per hour.
