Question

Hi, my phone is being weird so I can't call me teacher and I just need help understanding this. PLEASE DON'T GIVE ME FULL ANSWERS! I'm not one for cheating :)
It starts off with:
Create a quadratic function, f(x), in vertex form. The a should be between 4 and –4, the h will be your birth month, and the k will be your birth day. Write your equation below.

Using complete sentences, explain how to convert your birthday function into standard form.

I started with f(x) = 1(x + 11)^2 + 21 (I was born November 21st)
I have standard form as: f(x) = x^2 + 66x + 21

Answer 1

I think I messed up a bit already… The standard form is f(x) = x^2 + 66x +384… I think

Answer 2

After this is where I have the most trouble, it says:
3) Create two additional quadratic functions, g(x) and h(x).
A. The function g(x) will open the same direction as f(x), have the same vertex, but will be narrower.
Function g(x):

B. The function h(x) will open in the opposite direction as f(x), have the same vertex, but will be wider than f(x).

Function h(x):

I don't know how to go about do this...
