Suppose f is a quadratic function that has roots at x=−4 and x=8, and f(0)=16 We will write a function formula for f.

Sketch a graph of f based on the information you are given.
We can write f as f(x)=c⋅(x−x1)(x−x2) where x1<x2and c is some constant number. What are the values of x1 and x2?
- x1=
- x2=
Replace x1 and x2 in the formula f(x)=c⋅(x−x1)(x−x2) with the values you found above.

Use the fact that f(0)=16 to determine the value of c.

c=
Write a function formula for f in terms of x.
