Hi, I am asking about a grade 10 to 12 level question. My question is the following: Given an equation like y = (1/2) (x3)^{2} + 6, when describing the distortion from the base curve y = x^{2} is it correct to say there is a vertical compression by a factor of 2, or by a factor of 1/2 ? Which is more correct? I have seen both versions in different high school texts, and I am now unsure which is more correct. Thankyou, Wayne Hi Wayne, I asked a number of people here and we are all in agreement that, since "compression" already indicates that the distortion is to make the curve "smaller", the correct term is comprression by a factor of 2. Cheers,Harley
