write the domain in interval notation

Step 1

*Given:*

The given function is f(x) = ln (*x*^{2} +7).

Step 2

*Calculation:*

In general, the domain of a ln function f(x) = ln (y) exist for all y>0.

From the given function, y = *x*2 + 7.

Thus, the domain of the given function exist for *x*2 + 7>0.

That is for *x*2 = -7.

Since x is in terms of square, *x*2&nb...
