Answer
$x^2+2\geq y$
Work Step by Step
According to the given graph and equation, our inequality is:
$x^2+2\geq y$
This includes the shaded area and the function itself (because we have an equals sign). Notice that we used a greater-than sign to shade the graph below the curve (down).
We confirm the inequality by plugging in $(0,0)$, which gives us:
$0^2+2\ge 0$
This is a true statement, so the inequality works.
