## Find the domain of the function f(x)=x2+1

Expert Solution

The domain of the function f(x)=x2+1 is (,)

### Explanation of Solution

Given information:Consider the function f(x)=x2+1

Calculation:

Recall the domain of a function is the set of input or argument values for which the function is real and defined.

Assume a function from real values to real values as shown in the figure below: From the above graph, given function have no undefined points.

Thus, the domain of the function f(x)=x2+1 is (,)
