The table is displayed using the specified values.

³ Problem

Find the vertex of the parabola, y = x(36 - x) using a table of

values.
Reminder: The vertex of the parabola is the point on the line

of symmetry of the parabola.

After searching close to x = 18, the point (18, 324) appears to

be the vertex of the parabola since it appears to be the turning

point of the set of points of this function. To search closer to

x = 18, change the Step value to see points closer to

(18, 324).

Start

Specified the starting value for the

independent variable, x.

Step

Specified the incremental value for the

independent variable, x. The step can be

positive or negative, but cannot be zero.

Auto

The TI-30XS MultiView™ calculator

automatically generates a series of

values based on table start and table

step.

Ask-x

Lets you build a table manually by

entering specific values for the

independent variable, x.
