Key Features of Functions

Front

What is the range of a function?

Back

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

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.

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.

Front

What is discrete data?

Back

Discrete data consists of distinct or separate values, often counted in whole numbers.

Front

What is continuous data?

Back

Continuous data can take any value within a given range and is often measured.

Front

What is an asymptote?

Back

An asymptote is a line that a graph approaches but never touches.

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis, represented as (0, y).

Front

What is a function?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

What is the domain of a function?

Back

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

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b.
