Flashcards in Graph Transformations Deck (6)
y=k x f(x)
The original graph is stretched parallel to the y- axis by multipling the whole function by a number (k). If the number is less than one the graph is squashed down instead
y=f(x) + a
the whole graph slides up and down on the y axis by a
y= f(x - a)
The whole graph slides to the left or the right by a. This one goes 'the wrong way.' negative a goes right, positive a goes left.
The x- stretch
When k is a multiplier the graph gets scrunched up on the x axis. When k is a divider the graph stretches out.
Reflection in x- axis
The entire graph is reflected in the x axis
