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.

no not all of them.

step-by-step explanation:

some of them have a square base.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
