3.To obtain other roots, press the left or right cursor key, or tap the left or right graph controller arrows.

If there is only one solution, the pointer does not move when you press the cursor key or tap the graph controller arrow.

The following are examples for other G-Solve commands.

0307 To obtain the point of intersection for two graphs y = x + 1 and y = x2

0308 To determine coordinates at a particular point on a graph

0309 To graph the function y = x(x + 2)(x – 2) and obtain its definite integral in the domain of 1 s x s 2

0310 To graph the function y = x3 – 1 and determine its inflection point

0311 To graph the function y = x2 x – 2 and obtain the volume of a solid of revolution as the line segment from x = 1 to x = 2 is rotated on the x-axis

3-7 Modifying a Graph

A graph can be modified in real time as you change its coefficients and/or variable values. The Graph & Table application provides you with two methods for modifying a graph.

“Direct Modify” changes the coefficient in the equation of the original graph. This method can be used when you are modifying a single graph.

“Dynamic Modify” changes the values assigned to common variables of multiple functions. Use Dynamic Modify when you want to modify multiple graphs at the same time.

uTo modify a single graph (Direct Modify)

0312 To graph the functions y = 2x2 + 3x – 1 and y = 2x + 1, and then find out how a change in the coefficients of each function affects the shape and position of the graphs

uTo modify multiple graphs simultaneously (Dynamic Modify)

0313 To graph the functions y = ax2 b and y = ax + b, and then find out how a change in variable a from 1 to 4 and a change in variable b from –2 to 2 affect the shape and position of each graph
