1. Why John Napier
Rocks!
(well, logs actually)

2. Complete each table of values ...
Let's see 2^x

4. x
ƒ(x) = 3
x x
ƒ(x) = 5 ƒ(x) = 2

5. What happens when the base of an exponential function is negative?
x
ƒ(x) = (-2)
≠ ƒ(x) = -2 x
x
ƒ(x) = (-2)

6. Sketch the
given function
AND it's inverse
on the graph.

7. Let's see 2^x
Then, sketch the graph of it's inverse ...

8. Sketch the
given function
AND it's inverse
on the graph.

9. Rewrite each table of values for the inverse of each function ...

10. The Anatomy Of A Power
exponent
3
2 = 8power
base
power

11. a
b=c log b c = a
b is the base
b is the base
a is the exponent a is the (exponent) logarithm
c is the power c is the (power) argument
A Logarithm is an Exponent
you're going to forget that
