Question

What is the quadratic function that is created with roots -3 and 1 and a vertex at (-1, -8)?

Answer 1

First, deal with the roots.
A polynomial function with roots a, b, c, d has the equation
y = (x - a)(x - b)(x - c)(x - d)

Using that, can you find a polynomial function with roots -3 and 1?
