P(x) = 12x / (1-x)
What are the critical points and where is P(x) increasing and decreasing?

  • Calculus - ,

    critical points are where P'=0 or is undefined.

    P' = 12/(x-1)^2
    Since P' is always positive, P is always increasing

    P'=0 never, so there are no min/max
    P' is undefined at x=1, the vertical asymptote.
