The graph of an absolute value function opens down and has a vertex of (-3,0). the domain of the function is ? the range of the function is ?

The domain of the function is:

                All real numbers i.e. (-∞,∞)

The range of the function is:

                     (-∞,0]

It is given that:

The graph of an absolute value function opens down and has a vertex of (-3,0).

This means that the graph of the function increases continuously in the interval (-∞,-3] and takes maximum value 0 when x= -3 and then decreases continuously in the interval (-3,∞).

Domain of a function--

It is the set of all the x-values for which a function is defined i.e. it is the set of all the values of the independent variable for which the function is defined.

Range of a function--

It is the set of all the values attained by a function.

                Hence, the range of the function is: (-∞,0].
