A function is shown below:

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

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

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

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

Answer 1

factor it, set it equal to zero, and solve for x...

for graphing, plug in a bunch of values for x, and graph similarly to the way you would graph a regular line.

Answer 2

for the factoring try factoring the first two terms by x^2 and you should see a more famigliar pattern

Answer 3

Thank you! @student_basil and @francesco.alemanno. :)
