Front

What is a nonlinear function?

Back

A nonlinear function is a function that does not form a straight line when graphed. Its graph can be a curve or any shape that is not linear.

Front

What does it mean for a graph to represent a function?

Back

A graph represents a function if every input (x-value) has exactly one output (y-value). This means that no vertical line can intersect the graph at more than one point.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input is associated with exactly one output. A relation can have multiple outputs for a single input.

Front

What does it mean for a graph to be increasing?

Back

A graph is increasing if, as the x-values increase, the y-values also increase. This indicates that the function is rising.

Front

What does it mean for a graph to be decreasing?

Back

A graph is decreasing if, as the x-values increase, the y-values decrease. This indicates that the function is falling.
