Exponential Function pg. 326

the function f is an exponential function if f(x)=b^x where b is a positive constant other then 1 and x is any real number

Horizontal Line Test pg. 336

a function f has an inverse if and only if each horizontal line intersects the graph of y=f(x) in at most one point
