These are several different functions that provide various information about an expression on a graph and display it to the user, such distance between two points, definite integral, etc. This lists which graph modes provide each function, as well as their purpose or meaning.

*Available on the following graph(s): Function Graph, Polar Graph, Parametric Graph, Density Plot, and Stat Plot.*

Will ask the user to select two points on the graph. The distance between these two points will be returned and displayed at the lower left of the graph display.

*Available on the following graph(s): Function Graph.*

Will ask the user to select two points on the graph on the current expression. The minimum value on this interval will be displayed at the lower left of the graph display.

*Available on the following graph(s): Function Graph.*

Will ask the user to select two points on the graph on the current expression. The maximum value on this interval will be displayed at the lower left of the graph display.

*Available on the following graph(s): Function Graph.*

Will ask the user to select two points on the graph on the current expression. The definite integral on this interval will be displayed at the lower left of the graph display. The definite integral on an interval is the area underneath the points selected. This area will be shaded.

*Available on the following graph(s): Function Graph and Parametric Graph.*

Will ask the user to select two points on the graph on the current expression. The arc length on this interval will be displayed at the lower left of the graph display.

*Available on the following graph(s): Function Graph.*

Will ask the user to select two points on the graph on the current expression. The mean value on this interval will be displayed at the lower left of the graph display. The mean value on an interval is the point at which the slope of a line tangent to the graph is equal to the slope of the two points selected. This tangent line will be drawn to express this.
