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. Using complete sentences, explain how to convert your birthday function into standard form. Graph your function. Include your graph below. Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

Answer 1

Vertex form is as follows:
y = a(x-h)2+k
So, the first part is explained. Choose a number between 4 and -4 for a.
Fill in the appropriate answers.

Answer 2

Standard form is ax+by=c. To get there, all you need to do is FOIL.
