Answer:

The answer is B.
$(2x+1)/(x^(2)-7) ,x\\eq √(7)$

Explanation:

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

Focusing on the denominator makes it equal to = 0

$x^(2) -7=0\\x^(2) =7\\x=+√(7),-√(7)$

If the denominator equals zero then the equation ends up undefined. A number over zero, zero can not go divided into a number.
