Transforming Functions Equation. Vertical Stretch or Compression. Jan 29 2015 A function presented as an equation can be reflected by applying transformations one at a time.
Sometimes by looking at a quadratic function you can see how it has been transformed from the simple function y x 2. Jan 29 2015 A function presented as an equation can be reflected by applying transformations one at a time. As you noted positive H is to the right negative H which shows up as y xh2 - k where the value of h is actually positive is to the left.
Positive k is up negative k is down.
Multiply the function by 2 Stretched function Simplify the new function. This is three units higher than the basic quadratic f x x2. As you noted positive H is to the right negative H which shows up as y xh2 - k where the value of h is actually positive is to the left. Transform the function by 2 in y-direction stretch.
