Arithmetic and Geometric

Sequence- Is an ordered list of terms or elements.

 

Arithmetic sequence formula- In an Arithmetic Sequence the difference between one term and the next is a constant. Also called the Common Difference.

 

Geometric sequence formula- In a Geometric Sequence each term is found by multiplying the previous term by a constant. Also called the Common Ratio.

Example:

2, 4, 8, 16, 32, 64, 128, 256, ...

This sequence has a factor of 2 between each number. Each term (except the first term) is found by multiplying the previous term by 2.

Finite sequence- Is a function with domain 1,2,3.

Infinite sequence- Is a function with domain 1,2,3,4.... etc.

Series- Is the sum of a sequence.

Explicit formula- Each domain is an answer not based on any values.

Recursive Formula- Each domain is a answer based on a previous answer.

Graphing Exponential Equations

Graphing Exponential Equations

Graphing Exponential Growth/Decay

1. Create the Parent Graph.

2. Identify A,H,K.

3. Create your new T-Chart.

• Domain: All real #'s.
• Range: y>k; when a is positive. y<k; when a is negative.
• Asymptote: y=k.

4. Draw Asymptote.

5. Graph new points.

• Exponential Formula: y=a×b^x-h+k
• a = multiplier.

a>1 = stretch
0<a<1 = compression
a< 0(negative) = flipped over x-axis.

• b = base

b>1 = whole #, growth, always increasing.

0<b<1 = fraction; decay, always decreasing.

B is never negative only the multiplier is.

• h = lf/rt; opposite
• k = up/dn

Compound Interest

Compound Interest

Interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. Compound interest can be thought of as “interest on interest,” and will make a deposit or loan grow at a faster rate than simple interest, which is interest calculated only on the principal amount.



 = [P (1 + i)ⁿ] – P

= P [(1 + i)ⁿ – 1]

Compound Interest = Total amount of Principal and Interest in future (or Future Value) less Principal amount at present (or Present Value)

Statistics

Statistics Data

Domain- x values
Range- y values
End Behavior- How you describe both ends of x and y
Absolute Max/Min- 1 point that is the highest/lowest on a graph
Local Max/Min- more then one point that is the highest/lowest in a graph
Interval of Increase- section of a graph where y values are increasing described in terms of x
Interval of Decrease- section on a graph where the x values decrease
X intercept- point that crosses the x axis
Y intercept- point that crosses the y axis
Symmetry- based on even or odd, even symmetric of y axis odd is symmetric about the origin
Even/Odd/Neiher-
Asymptotes- imaginary line that get closer to the axis but never touches
                                 
Function- passes the vertical line test
One to One- passes vertical and horizontal line test
