Example 2 To determine the maximum value for the interval defined by start
point a = 0 and end point b = 3, with a precision of n = 6 for the
function y = –x
2
+ 2x + 2
Input f(x).

Input the interval a = 0, b = 3.
a,d,
Input the precision n = 6.

•In the function f(x), only X can be used as a variable in expressions. Other
variables (A through Z, r,
θ
) are treated as constants, and the value currently
assigned to that variable is applied during the calculation.
•Input of n and the closing parenthesis following the precision value can be
omitted.
•Discontinuous points or sections with drastic fluctuation can adversely affect
precision or even cause an error.
•Note that you cannot use a Solve, differential, quadratic differential, integration,
maximum/minimum value or Σ calculation expression inside of a maximum/
minimum calculation term.
•Inputting a larger value for n increases the precision of the calculation, but it
also increases the amount of time required to perform the calculation.
• The value you input for the end point of the interval (b) must be greater than
the value you input for the start point (a). Otherwise an error is generated.
•You can interrupt an ongoing maximum/minimum calculation by pressing the
A key.
•You can input an integer in the range of 1 to 9 for the value of n. Using any
value outside this range causes an error.
