Front

What is a function in mathematics?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What is the vertical line test?

Back

The vertical line test is a method to determine 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 does it mean for a graph to not start at the y-axis?

Back

It means that the represented scenario does not begin at the origin (0,0) and may involve an initial condition or delay.

Front

What is a mapping in mathematics?

Back

A mapping is a way to describe how each element in one set corresponds to an element in another set.

Front

What is the difference between a linear and a nonlinear graph?

Back

A linear graph represents a straight line and shows a constant rate of change, while a nonlinear graph represents a curve and shows a variable rate of change.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, written in the form (x, y).

Front

What does it mean if a graph passes the vertical line test?

Back

If a graph passes the vertical line test, it means that for every x-value, there is only one corresponding y-value, confirming it is a function.

Front

What is a domain in a function?

Back

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

Front

What is a range in a function?

Back

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

Front

What is a discrete function?

Back

A discrete function is a function that has specific, separate values, often represented by distinct points on a graph.
