REVIEW Relations and Functions REVIEW

Front

What is the Domain?

Back

The set of all possible input values (x-values) for a function.

Front

What is the Range?

Back

The set of all possible output values (y-values) for a function.

Front

What does the Vertical Line Test determine?

Back

It determines if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a Function?

Back

A relation where each input has exactly one output.

Front

What is an Ordered Pair?

Back

A pair of numbers (x, y) that represent a point on a graph.

Front

What are Quadrants in a Cartesian Plane?

Back

The four sections of the coordinate plane, labeled I, II, III, and IV, based on the signs of x and y.

Front

What is a Linear Function?

Back

A function that graphs to a straight line, typically in the form y = mx + b.

Front

What is a Non-Linear Function?

Back

A function that does not graph to a straight line, such as quadratic or exponential functions.

Front

What is a Relation?

Back

A set of ordered pairs, which can represent a function or not.

Front

What is the difference between Domain and Range?

Back

Domain refers to input values (x), while Range refers to output values (y).
