Explanations and definitions

Intercept -the point at which a line intersects a coordinate axis

Vertex -the point of intersection of lines or the point opposite the base of a figure

Exponent- a mathematical notation indicating the number of times a quantity is multiplied by itself

Radical – a sign that is put n front of an expression to denote that a root is to be extracted

Root – a number that when multiplied by itself some number of times equals a given number

Function – mathematical relation such that each element of one set is associated with at least one element of another set

Variable – a quantity that can assume any of a set of values

ed Pair – corresponding X and Y points on an X-Y coordinate plane

Coordinate System – a system that uses coordinates to establish position

Independent Variable – a variable in a logical or mathematical expression whose

value determines the dependent variable if f (x y , x is the independent variable

Dependent Variable – a variable in a logical or mathematical expression whose value depends in the independent variable if f (x y , y is the dependent variable
