Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, as x increases, f(x) also increases.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing on an interval if, as x increases, f(x) decreases.

Front

Define x-intercept.

Back

The x-intercept is the point where the graph of a function crosses the x-axis (y=0).

Front

Define y-intercept.

Back

The y-intercept is the point where the graph of a function crosses the y-axis (x=0).

Front
