Quadratics
5.4 Practicing Graphing … Heading to a BIG IDEA!
Lesson materials located below the video overview.
SETTING THE SCENE
We’ve been adjusting the equation \(y=x^2\) to give new equations whose graphs are the same U-shaped graph we see from \(y=x^2\) but shifted horizontally, shifted vertically, and made steeper or broader and upward or downward facing.
For example, if asked to
Sketch \(y=3\left(x-5\right)^2+10\),
we can first recognize this as the basic \(y=x^2\) equation
but with \(x=5\) behaving like zero
and made steeper with a steepness factor of \(3\)
and with all data points shifted \(10\) units higher.
The following picture summarises all that we just saw …
