Graphing Exponential

Growth:
Example:
when a > 0 and the b is greater than 1, the graph will be increasing (growing).
For this example, each time x is increased by 1, y increases by a factor of 2.

Such a situation is called Exponential Growth.


Decay:
Example:
when a > 0 and the b is between 0 and 1, the graph will be decreasing (decaying).
For this example, each time x is increased by 1, y decreases to one half of its previous value.

Such a situation is called Exponential Decay.

Compound Interest

Definition
When the interest rate is applied to the original principal and any accumulated interest, this is called compound interest.

General forms of a Sequence:
Sequence:  list of numbers
Arithmetic:  sequence of numbers such that the difference between the consecutive terms is constant.
                      
Arithmetic SequenceCommon Difference, d
1, 4, 7, 10, 13, 16, ...
d = 3
add 3 to each term to arrive at the next term,
or...the difference  a2 - a1 is 3.
15, 10, 5, 0, -5, -10, ...d = -5add -5 to each term to arrive at the next term,
or...the difference  a2 - a1 is -5.
add -1/2 to each term to arrive at the next term,
or....the difference a2 - a1 is -1/2.

Geometric: sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Characteristics of Graphs:


Domain- x values

Range- y values

End behavior-Describes whats happens to a graph on "both" ends

Absolute Max/Min- Highest/Lowest point

Local Max/Min-More than 1 high/low point

Interval Increasing-what happens to a graph ( y values) as you move along x axis if y values are up along x axis if y values are down.

Interval of Decrease- what happens to a graph as you move down along x-axis if y values are down.

X-Intercept-(a,o)

Y-Intercept-(b,o)

Symmetry- even= symmetric about the y-axis.

Even/Odd-add-symmetric about the y axis. If its neither then its none.

Asymptotes- imagery line that a graph gets closer and closer but never touch.

Function: describing what happens to a graph 

One to One: passes both vertical and horizontal line test
