Genreral Forms of a Sequnce

Arithmetic and Geometric Sequnces

Arithmetic Sequence: a_n= a₁ + (n-1)d

a₁=first term

d=difference

a_n=undefined variable

Geometric Sequence:  a_n= a₁ • r^n-1

Characteristics of a graph

 Characteristics & Traits

• Domain - x values
• Range - y value
•  End Behavior - the description of what happens to a graph at both ends
• Absolute Max/Min - the highest and lowest point on the graph
• Local Max/Min - More than 1 of the highest and lowest points on a graph

• Interval of Increase - what happens to a graph (y value) (how high) as you move along the x axis
• Interval of Decrease - what happens to a graph (y value) (how low) as you move along the x axis
• X Intercept - where the graph passes the X axis
• Y Intercept - where the graph passes the Y axis

• Odd Symmetric - rotational symmetry about origin
• Even Symmetric - symmetric about Y-axis
• Neither Symmetric - None
