Question

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.

Answer 1

What do you want a, h, and k to be?

Answer 2

H=1 K=29 A=2

Answer 3

f(x)=a(x-h)^2 + k

Answer 4

So, f(x)=2(x-1)^2 + 29

Answer 5

Do you know how to FOIL?

Answer 6

ohhh okay got it! and by any chance do you know how to convert it into standard form? can you like explain to me how

Answer 7

First you have to simplify it so FOIL it out and combine any like terms.

Answer 8

f(x)=2(x-1)(x-1)+29
f(x)=2(x^2-2x+1)+29
f(x)=2x^2-4x+2+29
f(x)=2x^2-4x+31

Answer 9

thank you for your help

Answer 10

So in standard form it would be
0=2x^2-4x+31
OR
2x^2-4x=31
