Graphing Functions

Front

What is the domain of a function?

Back

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

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 function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.

What does it mean for a function to be discrete?

Back

A function is discrete if it consists of distinct, separate values, often represented as individual points on a graph.

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the output value when the input is zero.

Front

How do you graph a linear function?

Back

To graph a linear function, identify the slope and y-intercept, then plot the y-intercept and use the slope to find another point.
