Parentheses, Exponents, Multiplication and Division, Addition and Subtraction

A collection of ordered pairs from 2 sets one object from each set

X values, input

The rate of change.

When the graph crosses the y-axis

multiplication and division are solved from left to right

A relation that assigns exactly one value from the range to one value of the domain

Y values, output

Rise over run

When the graph crosses the x-axis

addition and subtraction are solved from left to right

What is a linear function? A function whose graph is a non vertical line

f(x)

m

ax+by=c

To say what the variable represents

What is a nonlinear function? A function whose graph is not a line.

Plug x value for x in equation

y= mx+b

y-y1= m(x-x1)

To get the variable by itself

The dependent variable is determined by the independent variable.

What does f(x) represent in function notation? y

y=dependent/output, m=slope, x=independent/output, b=y-intercept

An equation with 2 or more variables
