The exponential function y=b^xhas a graph, which is a smooth curve.

 You can sketch the exponential curve by plotting some points. Plot at least 3 points

Example 1

Sketch y=5^x pick points for x

Example 2

Sketch y=(1/2)^x

The logarithmic function y=log_bx is also a smooth curve

Example 3

Sketch y=log_bx

You can rewrite y=log_bx as an exponential function 5^y=x (Plug in values for y and figure out x)
