Compression by a factor of ? 
20010112 

From Wayne: 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. Answered by Harley Weston.
