Key Features of Graphs

Front

What is the interval of increase?

Back

The interval of increase is the range of x-values where the graph rises. For example, from 3 to 7.

Front

What is the minimum of this graph?

Back

The minimum of the graph is the lowest point on the graph. For example, (-0.5, -3.5) is the minimum.

Front

Find the y-intercept(s) of the graph shown.

Back

The y-intercept is the point where the graph crosses the y-axis. For example, (0, 4) is the y-intercept.

Front

Does the graph have a maximum or minimum?

Back

The graph can have a maximum, minimum, both, or neither. In this case, it has a minimum.

Front

What is the y-intercept?

Back

The y-intercept is the point where the graph intersects the y-axis. For example, (0, 7) is the y-intercept.

Front

What does it mean for a graph to be increasing?

Back

A graph is increasing when the y-values rise as the x-values increase.

Front

What does it mean for a graph to be decreasing?

Back

A graph is decreasing when the y-values fall as the x-values increase.

Front

What is a maximum point on a graph?

Back

A maximum point is the highest point on the graph within a given interval.

Front

What is a minimum point on a graph?

Back

A minimum point is the lowest point on the graph within a given interval.

Front

How do you find the x-intercept of a graph?

Back

The x-intercept is found where the graph crosses the x-axis, which occurs when y=0.
