Hello,I need help with the following question. 9. Find the domain and range of the function shown.y 4 (-2,2)(2,2) x -5 5-4 If the graph is that of a function, what are the domain and range of the function? Select the correct choice below and fill in any answer boxes within your choice.A. The domain is . The range is . (Type your answers in interval notation.)B. The graph is not a function.A screenshot is posted below

Answer 1

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

A.

From the graph, we can conclude:

The domain is:

`(-\infty,\infty)`

The range is:

`(-\infty,2\rbrack`

B.

A function is a specific type of relation in which each input value has one and only one output value. Therefore, this graph represents a function
