Graphing The Solution; Solver Graph Tools - Texas Instruments TI-86 Manual Book

The graph to the right plots
the solution from the example
on page 202. The window
variable values are:
xMin=L10
yMin=L50
xMax=50 yMax=50
You can use the free-moving
cursor or trace cursor to
select a guess on the graph.

Graphing the Solution

When you select
GRAPH
solver graph is displayed with the free-moving cursor.
The vertical axis represents the result of the left side
of the equation minus the right side of the equation
(left right) at each independent variable value.
N
The horizontal axis represents the independent
variable for which you solved the equation.
On the graph, solutions exist for the equation where
intersects the x-axis. The solver graph:
Uses the current window and format settings (Chapter 5).
Does not graph the solution according to the current graphing mode.
Always graphs a solution as a function graph.
Does not graph selected functions or turned on stat plots along with the solution.

Solver Graph Tools

You can explore the graph of a solution with the free-moving cursor, as you would on any
other graph. When you do, the coordinate values for the variable (the x-axis) and the value
(the y-axis) are updated.
