Which statements are true about the function f(x) = x3 + 2x² - 9x - 18?
Select all that apply.
☐
As a approaches-00, f(x) approaches -00, and as x approaches
∞, f(x) approaches ∞.
As a approaches-00, f(x) approaches oo, and as z approaches ∞,
f(x) approaches -0.
The function has a relative minimum between the z-values -3 and -2,
and it has a relative maximum between the x-values -2 and 3.
The function is positive over the intervals (-3, -2) and (3,∞), and
the function is negative over the intervals (-00,-3) and (-2, 3).
