Which is true regarding the function?

Answer:

  f(–6) = 10

Step-by-step explanation:

Each ordered pair represents the pair (x, f(x)).

The domain (set of possible x-values) is the list of first numbers in the pairs:

  {8, 0, 1, 2, -6}

Any number not on this list will not appear as x in f(x). This eliminates f(-3) and f(3).

The pair for f(8) is (8, -3), so f(8) = -3, not 0.

The pair for f(-6) is (-6, 10), so f(-6) = 10, as shown in the last answer choice.
