Classifying Data
Relation vs Function
Relation: Relationship between data
Function: One input has only 1 output
Functions
Graph: Vertical Line Test
Arrow Diagram: x-value has 1 y-value
Domain & Range: Number of values in the domain must be => number of values in the range
Equations: Degree of y must be odd
Ordered Pairs: No repeated x values
Discrete and Continuous Data
Discrete: Data can only take on a specific value
Continuous Data: Data can take on any value in a range
Linear and Non-Linear Functions
Linear: Function increases or decreases at a constant rate
Non-Linear: Function does not increase or decrease at a constant rate
Slope: The rate of change: rise/run
Domain and Range
ε : means belongs to
{ } : means the set of
l : means such that
syntax : {{x l xεR}}
Function Notation: f(x) = 3x + 1 (f(x) is y because y is a function of x)
