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).

Specified the starting value for the
independent variable, x.
Specified the incremental value for the
independent variable, x. The step can be
positive or negative, but cannot be zero.
The TI-30XS MultiView™ calculator
automatically generates a series of
values based on table start and table
step.
Lets you build a table manually by
entering specific values for the
independent variable, x.
