What is a function in mathematics?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

How can you determine if a relation is a function?

Back

A relation is a function if every x-value has only one corresponding y-value.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and has a constant rate of change.

Front

What is the slope of a linear function?

Back

The slope of a linear function is the ratio of the change in y to the change in x, representing the steepness of the line.

Front

What is a y-intercept?

Back

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

Front

If a function has a constant rate of change, what can you conclude about its graph?

Back

The graph of the function will be a straight line.

Front

What is the next number in the sequence: 1, 3, 5, 7, ...?
