A function is shown below:

f(x) = x3 + 4x2 - x - 4

Part A: What are the factors of f(x)? Show your work. (3 points)

Part B: What are the zeros of f(x)? Show your work. (2 points)

Part C: What are the steps you would follow to graph f(x)? Describe the end behavior of the graph of f(x). (5 points)

Answer 1

x3 + 4x2 - x - 4

an expression of 4 terms means we want to find either
- a perfect square trinomial
- two binomials

can you see if there is a perfect square trinomial?

Answer 2

There isn't one? (:

Answer 3

here is hint: what about..
4x2 - x - 4

if
4 = 2^2

then
4x2 - x - 4
= (2x)^2 - x - (2)^2
