WebActually, the normal distribution is based on the function exp (-x²/2). If you try to graph that, you'll see it looks already like the bell shape of the normal function. If you then graph exp (- (x-mu)²/2), you'll see the same function shifted by its mean - the mean must correspond to the function's maximum.
