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.
Procedure â€”
To Graph a Logarithmic Function
Step 1 Rewrite y = log_{b}x in exponential form, x = b^{y}.
Step 2 Switch x and y to get y = b^{x}.
Step 3 Calculate ordered pairs.
Step 4 Exchange the x and ycoordinates.
Step 5 Graph the new ordered pairs.
Note:
If you need to graph a function
that is in the form y = log_{b}x,
first rewrite it in exponential form.
