3-5 Maximum/Minimum Value Calculations
After displaying the function analysis menu, you can input maximum/minimum
calculations using the formats below, and solve for the maximum and minimum of
a function within interval
a < x < b .

Example 1 To determine the minimum 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 – 4 x + 9
Input f (x) .
