k Maximum/Minimum Value Calculations [OPTN]-[CALC]-[FMin]/[FMax]
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. (a: start point of interval, b: end point of interval, n: precision (n = 1 to 9))
