1. Exponential Equations
Objective: Students will be able to write and interpret exponential equations.

2. Exponential Equations
Growth and Decay Graph grows quicker than just a square or cubed Looking at percentage growth and decay
a is y intercept, when x =0
b is what is being repeatedly multiplied
b>1 growth
b<1 decay

3. Growth a variables mean the same thing except r
r is the percent that you are going, such as a population
(1+r) is the b value

4. Decay
Similar to growth except you subtract r because your population is going down
(1-r) is the b value

5. Finding from a table Look for when x = 0 this will give you a
Look for pattern in the y values, always multiplication, division is just multiplication of a fraction

6. Example X Y 2 1 6 18 3 54 X=0 y is 2 this is the a value2 1 6 18 3 54
X=0 y is 2 this is the a value
Constantly multiply by 3

7. Example X Y 4 1 2 3
A=4
B=1/2
