Range

Front

Set of all output (y) values you can plug into a function

Back

Growth factor

Front

The "b" in y=ab^x. The rate at which something is growing or decaying.

Back

Direct Variation

Front

Linear function defined by an equation y=kx where k is not equal to 0.

Front

y=x^2

Back

Parent Function

Front

The simplest function

Back

Quadratic Equation

Front

an equation with degree of 2

Back

Asymptote

Front

A line that the graph of a function gets closer to as x or y gets larger but never touches

Back

Slope

Front

Steepness of a line

Back

Positive Correlation

Front

The relationship between two sets of data in which both sets of data increase together.

Back

Exponential function

Front

A function that repeatedly multiplies an initial amount by the same positive number. y=ab^x

Back

Slope-Intercept Form

Front

Form of linear equation where m = slope and b = y-intercept.

Back

Perimeter

Distance around a shape.

Back

Function

Front

A relationship where every input value (x) has one and ONLY one output value (y) X does not repeat!

Back

Initial amount

Front

Also called roots, zeros or x-intercepts

Back

Constant of variation

Front

When a line decreases

Back

Standard Form

Front

Ax+By=C where A, B, and C are real numbers and A & B are not both zero.

Linear equation

Front

An equation whose graph forms a straight line.

Back
