Determine the domain and the range of the graph. Express your answer in interval notation
The domain is the interval of the possible values of $x$. As we can see from the graph, the domain is infinity because the parabola extends infinitely.
The range is the interval of the possible values of $y$. In this case, we see that the $y$ values cannot go below $-2, $ but they extend towards positive infinity.
Therefore, the domain is $\boxed{(-\infty, +\infty)},$ and the range is $\boxed{(-2, +\infty)}. $
