Chapter 9: Polynomial Functions Chapter Review Mrs. Parziale

A piece of cardboard is 30” x 12”. If the four square corners (each length x)are cut out to make a box, what is the polynomial expression that represents the volume of this box? 12” 30” x

Given the polynomial expression for volume of the previous problem, If the manufacturer wants to create a box that would give him the maximum volume, what length should the sides of the cutout corners be? What maximum volume does this give the manufacturer?

Long Division Divide using long division.

Long Division Divide using long division.

Synthetic Division Divide using synthetic division.

Factor Factor over the set of complex numbers:

Factor Factor completely over the set of complex numbers (hint – graph and find one zero – then use synthetic division to find the quadratic so you can use the quadratic formula)

Give a possible polynomial in factored form if the solutions for x are:

Factor Completely Factor completely when (x + 2) is one factor.

Graphing Graph the following function: Find – Y-intercept – Zeros – Absolute min, max – Relative min – Relative max

Find – Interval where function is positive – Interval where function is negative – Interval where function is increasing – Interval where function is decreasing

Given Find r + s Find rs What is the complex conjugate of s? Find Rationalize the denominator.
