1
FINDING THE EQUATION OF A QUADRATIC FUNCTION Foldable

2
STEP 1 (INSIDE ON THE LEFT) Find the vertex (h, k) Find the coordinate of another point (x, y) on the parabola

3
STEP 1 (INSIDE ON THE RIGHT) Vertex = (1,0) h = 1 K = 0 Pick a point: = (2, 1) X = 2 Y = 1

4
STEP 2 (INSIDE ON THE LEFT)

5
STEP 2 ( INSIDE ON THE RIGHT) Vertex = (1, 0) h = 1 k = 0

6
STEP 3 (INSIDE ON THE LEFT) Rewrite the equation with the (x, y) substituted in.

7
STEP 3 (INSIDE ON THE RIGHT)

8
STEP 4 (INSIDE ON THE LEFT) Now, solve algebraically for the variable “a”!

9
STEP 4 (ON THE RIGHT SIDE)

10
STEP 5 (INSIDE ON THE LEFT) Substitute a, h, and k into your original equation.

11
STEP 5 (INSIDE ON THE RIGHT) h = 1 k = 0 a = 1

12
STEP 6 (INSIDE ON THE LEFT) Put your new function into simplest form.

13
STEP 6 (INSIDE ON THE RIGHT)
