What is Exponential Functions ?
Exponent Laws Review:

A) Ax / Ay = A(x + y)
B) Ax / Ay = A(x - y)
C) (ABC)x = AxBxCx
D) ((Ax)y)z = Axyz
E) (A/B)x = Ax /Bx

Definition of Exponents: For any real number a, a > 0, and any real number x, ax is a unique real number.
In functional notation:
f (x) = ax (a > 0)
Example 1: Graph y = 2x.

Solution: Find some points that satisfy the equation by setting x and finding y. Graph the points.
