A student divided f(x) = 3x3 + 8x2 + 53 - 4 by x + 2 and found the remainder was r = -6. Based on the remainder theorem, what can be concluded about f(x)?

The point (-2,-6) lies on the graph of f(I).

The function f(x) = 323 + 8x2 + 53 - 4 has a zero at -6.

The function f(x) = 313 + 8x2 + 5x - 4 has a zero at -2.

The y-intercept of the graph of f(x) is-6.
