Relations - A set of ordered pairs Function - A relation in which every input has exactly one output Vertical Line Test - Method used to determine if a relation is a function. If any vertical line intersects a graph more than once, then the graph is not a function. Linear Function - Function in which the points increase by a constant rate and can be written as y=mx+b where y is the dependent variable, x is the independent variable, and m and b are real numbers. Exponential Function - Function where the variable or input is an exponent in the form of f(x) = ab^x, when a and b are real numbers, b > 0, and b does not equal 1. End Behavior - the behavior at the ends of a graph Sequence - a list of values Explicit Definition - A presentation of a sequence than can find any term in the sequence Recursive Definition - A presentation of a sequence that relies on the previous term to find the next term in the sequence Arithmetic Sequence - A sequence in which the terms increase or decrease by a set amount |
