EXPLANATION
The vertex of the graph is at

The equation of the graph in vertex form is given by the formula,

The above graph has a minimum point, hence

When we put these values into the equation we obtain,

This implies that,

The point (-2,0) lies on the line.



The correct answer is D.
For this case we have the following function:

By definition, we have that the domain of a function is given by all the values for which the function is defined. The given function is not defined when the denominator is zero.
So:

Thus, the function is not defined at 
The domain is given by all real numbers except 2.
