what are the inflection points of 5x^2-45/x^2-25

  1. Damon

    what is the numerator and what is the denominator?

  2. Steve

    assuming the usual sloppiness, we have

    y'= -160x/(x^2-25)^2
    y" = 160(3x^2+25)/(x^2-25)^3

    since y" is never zero, there are no inflection points, as can be confirmed here:^2-45%29%2F%28x^2-25%29
