Consider function f. f(x) = x³ + 2x² - 5x - 6 Select the locations of the zeros of function f on the coordinate plane. Then select the end behavior of its graph. (multiple answers)

1. As x approaches positive infinitely, f(x) approaches negative infinitely.

2. As x approaches negative infinitely, f(x) approaches negative infinitely.

3. As x approaches negative infinitely, f(x) approaches positive infinitely.

4. As x approaches positive infinitely, f(x) remains constant.
