I think you misunderstood me...that's the book's answer, but I don't know how they got it. My questions are in blue at the bottom.

Uh, Soroban, that picture is copied from the answer key and is what janedoe is asking about!(Evilgrin)

janedoe, exactly how you would put it into a calculator depends on the calculator.

You certainly should be able to put in , for the straight line. The parabola is, of course, [tex]y2= 2x- x^2[/itex].

Finally, they know it is "similar to graph of the derivative of f(x)" because the derivative is given by and 0.01 is not very far from 0.
