Question

Graph the following relation. Use the graph to find the domain and range (in interval form) and indicate whetherthe graph is the graph of a function.y = -4 Domain: Range { }

Answer 1

Given:

$y=-4$

Required:

To draw the graph and find the domain and range.

Explanation:

The graph of the function will be,

We know that,

The domain is the set of all input values for the function and the range is the set of all output values for the function.

Therefore, we get,

$\begin{gathered} Domain:(-\infty,\infty) \\ Range:\lbrace-4\rbrace \end{gathered}$

Yes, it is a function.

Because each input value has exactly one output value.

Final answer:

$\begin{gathered} Domain:(-\infty,\infty) \\ Range:\lbrace-4\rbrace \end{gathered}$

And it is a function.
