WebSuppose we need to graph f (x) = 2 (x-1) 2, we shift the vertex one unit to the right and stretch vertically by a factor of 2. Thus, we get the general formula of transformations as. f (x) =a (bx-h)n+k. where k is the vertical shift, h is the horizontal shift, a is the vertical stretch and. b is the horizontal stretch.
