Best ResponseYou've already chosen the best response.0Yes, it would be. The range would be from [1,1] to [4,4] Therefore it stretched vertically from a factor of 4.

Best ResponseYou've already chosen the best response.0It cant be horizontal because only the y coordinate are increasing. If it was cos(xpi/2) from cos(x), then it would have a horizontal or compressional factor.
