PLEASE HELP!!!! The graph of an absolute value function opens down and has a vertex of (0, -3). Find the domain and range.

Domain:
A) [-3, ∞ )
B)( -∞ ,-3]
C)(- ∞ , ∞ )

Range:
A)(- ∞ , ∞ )
B)[-3. ∞ )
C)(-∞ ,-3]

Answer:

Step-by-step explanation:

This function has a maximum value, which occurs at the vertex, (0, -3).  The maximum value is thus -3.  The domain is "the set of all real numbers," and the range is (-∞, -3].
