Take the following graph
In order to recreate (one possible) function we need to do the following:
- Determine the end-behavior, and decide if it’s a reflection or not (this one is a reflection of a ^2!)
- Determine its stretch/squash
- count the squares, if its over more than 1 then add that many as the denominator (the above would be 1/2) and you got the coefficient!
- Otherwise if its taller more than 1 before it crosses a point add that many and add that as the coefficient!
-
- This would be 2!
- Think of it like when you find the slope, by going
-
- Next add the adjustments to the vertex as appropriate! inside the parathesis for horizontal movement and outside for vertical movement
