Graphing Logarithmic Functions
We can graph a logarithmic function by using the fact that the inverse of a
logarithmic function is an exponential function.
Hereâ€™s the procedure to graph a logarithmic function.
To Graph a Logarithmic Function
Step 1 Rewrite y = logbx in exponential form, x = by.
Step 2 Switch x and y to get y = bx.
Step 3 Calculate ordered pairs.
Step 4 Exchange the x- and y-coordinates.
Step 5 Graph the new ordered pairs.
If you need to graph a function
that is in the form y = logbx,
first rewrite it in exponential form.
