1. Identify all the real roots of the equation:
3x3 - 18x2 – 9x + 132
2. Identify whether the degree is odd or even,
whether the leading coefficient is positive or
negative, describe the end behavior, and
sketch the graph without using the
calculator:
2x3 + 3x2 - 4x

the length is 3x – 5, write an expression that
represents the width. (Hint: do long
division!)
