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:
[tex](-\infty,\infty)[/tex]
The range is:
[tex](-\infty,2\rbrack[/tex]
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
