PRESENTATION OUTLINE

Functions and Graph

By: Camille Omnes 

Function

 each element of the domain is paired with one of the range

Untitled Slide

Untitled Slide

Domain

the set of all inputs, or x-coordinate, of the ordered pairs

Untitled Slide

Range

the set of all outputs or y-coordinates of the ordered pairs

Untitled Slide

Linear Equation

two variables is an equation written in the form ax+by=c

Untitled Slide

Dependent Variable

 y is the dependent variable  

Untitled Slide

Independent Variable

x is the independent variable

Untitled Slide

Slope

slope of a non-vertical line is a horizontal and a vertical line is undefined 

Untitled Slide

Point Slope Form

y-y1+m(x-x1) "m" is the slope of the line and (x1,y1) is a point on the line

Untitled Slide

Slope Intercept Form

y=mx+b m is the slope and b is the y-intercept 

Untitled Slide

Vertical Line Test

determine if the relation has one element of domain paired with more than one range; if not, it's not a function

x-intercept

point where a line crosses the x-axis

y intercept

point where a line passes the y-axis
