Compound Interest Formula

Graphing Exponential Growth/Decay

y=a*b(x-h)+k


a=multiplier (determiners the direction)


a>1=stretch


0<a<1=compression

a<0 negative = flipped over x axis


b-base (never a negative base)


b>1=growth (always increasing)


0<b<1= Decay (always decreasing)


h=lt/rt


k=up/down


range y>k is positive


Asymptote- y<k is negative

General forms of a sequence

Sequence-is an ordered list of terms or elements.
Sequence

Finite sequence-is a function with domain 123.

Infinite sequence-is a function with domain 1234....

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.

Arithmetic formula- In an Arithmetic Sequence the difference between one term and the next is a constant.

Geometric sequence-In a Geometric Sequence each term is found by multiplying the previous term by a constant.

Characteristics of Graphs

Domain- is x values
Range- is y values
End behavior- describing the ends of a equation. The graph below is even degree with positive leading coefficient.

Absolute max/min- one point that is highest/lowest point on a graph




Local max/min- more then on point that are the highest/lowest points on a graph




Interval of increase-section of a where y values are increasing
Interval of decrease- section of a graph where x values are decreasing



X intercept- vertical line, where crosses x axis
Y intercept- horizontal line, where crosses y axis

Symmetry- Even there is symmetry about the y-axis (like a reflection)
                   Odd there is symmetry about the x axis
                   Neither there is no symmetry

Asymptotes-imaginary line that get closer but never touches the axis
Function-passes the vertical line test
One to One-passes the vertical and horizontal line test
