A student wants to graph the function f(x) = -x^3- 4x^2+ 9x + 36. Which characteristics will help the student graph the function correctly?
A
B
For large values of x, f(x) decreases as x increases, and the function has x-intercepts at
(-4,0),(-3,0), and (3,0).
For large values of x, f(x) decreases as x increases, and the function has x-intercepts at
(-4,0) and (3,0) only.
