**Ignore?**

Polynomial function

The graph crosses the x-axis up to n times and has up to n - 1 vertices (points where the function changes direction). The domain is all real numbers.

Quadratic Function

a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero

Linear Function

y = mx + b

direct variation function

The straight-line graph goes through the origin. The domain is x ≥ 0 (as shown) for most real-world applications.

Power function

The graph contains the origin if b is positive. In most real-world applications, the domain is nonnegative real numbers if b is positive and positive real numbers if b is negative.

Exponential Function

y = ab^x

Inverse Variation function

Both of the axes are asymptotes. The domain is x ≠ 0. For most real-world applications, the domain is x > 0.

Rational Algebraic function

A rational function has a discontinuity (asymptote or missing point) where the denominator is 0; it may have horizontal or other asymptotes.

Absolute Value Function

any f(x) = | x |

Linear-Piecewise Function

- Many different line segments put together to form one graph

ordered pair

A pair of numbers that can be used to locate a point on a coordinate plane.

Relation

A Smart Art graphic type that compares connections between concepts.

y-intercept

the point where the line crosses the y-axis

x-intercept

the point where the line crosses the x-axis

vertex

The point where two sides meet. (Shared end points of the line segments of a polygon.)

power funciton

f(x) = axb (a variable with a constant exponent)

exponential

domain-all real numbers

linear

A relationship that graphs as a straight line. This means y is changing at a constant enterval.

f(x)=ax

Direct Variation

quadratic

2nd degree

power

a number produced by raising a base to an exponent

f(x)=a/x^n

Inverse Variation

y=mx+b

Line equation

ax+by=c

How do you write an equation in standard form?

y=ax^2+bx+c

Quadratic (Standard Form)

y=kx

Direct Variation

y=k/x

inverse variation

y=a*r^x

Exponential (Standard Form)

y=x

(x,y)-(y,x)

y=x^2

Quadratic (Parent Function)

y=2/x

Inversely Proportional (Parent Function)

f(x)=mx+b

linear function

f(x)=ax^2+bx+c

Quadratic (Function Notation)

f(x)=kx

Directly Proportional (Also linear) (Function Notation)

f(x)=k/x

Inversely Proportional (Function Notation)
