Unit 6 - Objective 2 - Graphs of y=bxand y=logbx
Quick Review


The exponential function y=bxhas a graph, which is a smooth curve.

 

Or

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


 

Example 1

 

Sketch y=5x pick points for x

 

 

 

Example 2

 

Sketch y=(1/2)x


 

The logarithmic function y=logbx is also a smooth curve

 

Example 3

 

Sketch y=logbx

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