    In y = editor insert your equation

    F2 zoom (zoomstd or zoom fit)

    F5 calc select min (and later max)

    The calc will require left-bound; arrow to left of TP you are finding then enter

    The calc will then require right-bound; arrow to right of TP you are finding then enter

    Sure about the restricted domain, there is a max at x = 0
