Answer
See graph
Work Step by Step
Given \begin{equation}
y>x^2-4 x-21.
\end{equation}
First, we will sketch the graph of the quadratic using a dashed curve because there is no "equal to" part.
Next, pick $(0,0)$ as a test point, we find that it does satisfy the inequality, so we will shade the points above the parabola.
