Sorry to be joining the "shifting and stretching" debate so late, but I =
suggest that those who wish to stop teaching this topic take a look at the =
calculus text written by the faculty at North Carolina School for Science =
and Math (published by Everyday?? which took over from Janson). I follow =
some of their approach, which includes looking at the derivative of a =
function which has been vertically shifted as having the same slope as the =
original function; of a function which has been horizontally shifted as =
having the same slope as the original function only shifted, etc. =20
