Vertical stretch/compression
Vertical stretch
a constant greater than 1 is vertically stretch
Vertical compression
a constant lower than 1 is vertically comprised
transforming by vertical stretch and vertical compression
Horizontal shift
What is Horizontal shift? Horizontal shift is when the parabola is being shifted to the left or the right. A way horizontal shift can be used is creating a chart to help

VERTEX-the point which a parabola changes direction
Y-INTERCEPT- the point were the parabola passes the the y-axis
MAXIMUM AND MINIMUM VALUE- y-coordinate of the axis
Second differences-common differences at the d2 if the x-value is changing by the same number
