Domain
|
Set of all input values (x)
|
|
|
Range
|
Set of all output values (y)
|
|
|
Vertex
|
The point (ordered pair) where the graph changes from increasing to decreasing or decreasing to increasing. Usually the minimum or maximum y-value of the graph.
|
|
|
Axis of symmetry
|
The imaginary vertical line about which a graph is symmetrical.
|
|
|
zeros
|
x-intercepts
|
|
|
intercepts
|
The points at which the graph crosses either the x-axis (x-intercept) or y-axis (y-intercept).
|
|
|
extrema
|
The y-coordinate at the vertex and/or vertices of the graph.
|
|
|
Points of discontinuity
|
The x-values on the graph where y has more than one (included or excluded) value.
|
|
|
Intervals over which a function is constant
|
The x-values on the graph where the graph is a horizontal line.
|
|
|
Intervals of increase and decrease
|
The x-values on the graph where y increases as x increases (increase) or where y decreases as x increases (decrease).
