Answer:

  (b)  -6 only

Step-by-step explanation:

There is only one point of intersection of the graph with the vertical line x=0. That is where the graph crosses the y-axis, at (0, -6).

  f(0) = -6  (only)

_____

Additional comment

The fact that f(x) is called a function means that f(0) can have only one value. This eliminates the last two answer choices. The graph crosses y=0 at several points, all having different x-values than x=0. f(0) ≠ 0, eliminating the first choice.
