A
A function whose graph on a Cartesian coordinate system is not a straight line.
3
Q
Domain
A
The set of all possible input values for a function or relation
4
Q

A
The set of all possible values for the output of the function.
5
Q
Vertical line test
A
A method used to check whether or not a relation is a function.
Imagine a vertical line moving horizontally along the x-axis. If this vertical line intersects the graph in at most one point at any x-coordinate, then the relation is a function. Otherwise, the relation is not a function.
