Graph y greater than or equal to -x^2 + 1

Shown below

First of all, we need to plot the equation:

The graph of this equation is a parabola. The vertex of this parabola lies on the point (0, 1) and the x-intecepts are the points (-1, 0) and (1, 0). But the problem asks for the graph of y greater than or equal to -x^2 + 1, that is, the inequality:

To find this, we choose a point on the Cartesian plane, say, (0, 0) and let's take a look to the inequality:

So the region does't contain point (0, 0), therefore the graph is the one shown below.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
