What is the y-intercept of a graph?

Back

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

Front

How do you determine the y-intercept from a graph?

Back

To find the y-intercept, look for the point where the graph crosses the y-axis.

Front

What does the end behavior of a graph refer to?

Back

End behavior describes how the values of a function behave as x approaches positive or negative infinity.

Front

What does it mean if a function is negative on an interval?

Back

A function is negative on an interval if its values are below the x-axis for all x in that interval.

Front

What does it mean if a function is positive on an interval?

Back

A function is positive on an interval if its values are above the x-axis for all x in that interval.

Front

What is the significance of the x-axis in a graph?

Back

The x-axis represents the input values (independent variable) of a function.

Front

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

Back

The y-axis represents the output values (dependent variable) of a function.

Front

How can you identify where a function is increasing on a graph?

Back

A function is increasing on an interval if the graph rises as you move from left to right.

Front

How can you identify where a function is decreasing on a graph?

Back

A function is decreasing on an interval if the graph falls as you move from left to right.

Front

What does it mean for a function to have a local maximum?

Back

A local maximum is a point where the function value is higher than all nearby points.
