A. Transform each quadratic function into standard form. Identify the constants h and k. - 1) y = x2 + 10x – 13 2) y = x2 - 6x + 5 3) y = x2 - 2x + 3 4) y = x2 – 3x + 16 5) y = x2 – 18x – 9 6) y = 2x2 – 3x + 4 7) y = 3x2 - 12x - 4 8) y = 2x2 - 8x - 22 9) y = 3x2 + 6x - 1 10) y = 9x2 + 18x + 4 - -

1. (-5,-12)

2. (3,-4)

To identify the constant H and K

- You need to write the given equation in vertex form

- Use complete the square method to write in vertex form

- The vertex form is

- after writing the equation in the world storm you can see that there is a h and a k

- Pull the h and the k in into (h,k)

I can't do all of it so I'll do 2 for you and with explanations.

p - 13 = 20

Step-by-step explanation:

p - 13 = 20

add 13 on both sides

p = 33

there were 33 pizzas in the library.
