Respuesta :

The domain of a function are all valid x values which are defined (appear on the graph) of the function. In this graph, all real numbers from negative infinity to positive infinity can appear, so the domain is all real numbers.

The domain of a graph is the possible x values of the graph.

The domain of the function is all real numbers

From the graph, we have the following observations

  • The x values extend infinitely in the positive direction
  • The x values extend infinitely in the negative direction

This means that:

The domain is : [tex](-\infty, \infty)[/tex]

Hence, the domain is the set of real numbers
