Answer:


\textbf{None of them. }\\

Explanation:


\textup{\textbf{For the points to be on the graph substitute for $x$ and $y$ and check for equality.}}\\\textup{The function given is:}\\$$ x^2 + 2x + 6 $$ \\\textup{Let us check for $(-3,21)$}\\


$ i.e., {(-3)}^2 + 2(-3) + 6 = 9 \\e 21 $\\\textup{That means the point is not on the graph.}\\\textup{Similarly, for $(-2,0)$ we see that}\\$ {(-2)}^2 + 2(-2) + 6 = 6 \\e  0 $\\\textup{Similarly check for $(-1,10)$ to find out that it isn't satisfied as well.}\\


\textup{\textbf{Hence, we conclude none of the points satisfy the equation.}}
