Graph Terminology

Front

Y-intercept

Back

Where the graph crosses the y axis.

Front

Asymptote

Back

An imaginary line that a curve gets closer and closer to. Where the graph 'flattens'. Always the back number in the equation.

Front

Domain

Back

A set of x values (lowest x, highest x).

Front

Range

Back

A set of all of the y values. (lowest y, highest y).

Front

End Behavior

Back

The y-values that the graph gets closer and closer to as you move towards the left and as you move towards the right.

Front

Increasing Decreasing

Back

From left to right, the graph is going up (increasing) or going down (decreasing). Interval of increase or decrease will be -∞ < x < ∞ because it is increasing or decreasing across the entire graph.

Front

Positive Negative

Back

Use x values to describe where the graph is above the x-axis (positive) or below the x-axis (negative). X intercept is where it changes. Often written as an inequality.
