Option c.

Step-by-step explanation:

We are given these following functions:

f(x) = 2x + 1

g(x) = x^2 - 7

Division:

The division of those functions is:

$\frac{f}{g}(x) = \frac{2x + 1}{x^2-7}$

Domain:

We have a fraction, so we have to take the domain of the function in consideration. The denominator cannot be 0, thus:

$x^2 - 7 \neq 0$

$x^2 \neq 7$

$x \neq \pm \sqrt{7}$

Thus, the correct answer is given by option C.
