Graph the learning curve L(x) = (x - 2)^3 +8

  1. Apr 28, 2005 #1
    having trouble getting started on this problem. I don't really know what to do first.

    A learning curve is a function L(x) that gives the amount of time that a person requires to learn "X" pieces of information. Many learning curves take the form L(x) = (x-a)^n + b (for x>0 or x=0), where "a", "b" and "n" are positive constants. Graph the learning curve L(x) = (x - 2)^3 +8.

    Just draw the curve. That's all you're being asked to do.

    It's just a cubic polynomial. Depending on what they expect, you may have to use the various derivatives to find maxima, minima, and/or points of inflection. Find them, and draw it!

    Thanks for the advice. Will do.
