8.3 Logarithmic Functions and their Inverses.
Make a table and graph y = 3x
Use your table find the inverse of y = 3x
ORIGINAL
INVERSE
You find inverses by switching the x and y and solving
for the new y.
y = 3x
x=
y
3
If y = bx then x = logby

Transformations of log graphs.
Graph y = log4x.
What is this graph the inverse of?
Now what if you wanted to graph y = log4(x - 2)?
What if you wanted to graph y = log4x + 3?
