Checking Points on the Graph of a Function

To determine whether the points A(1, -1), B(-1, 1), and C(-2, -4) belong to the graph of the function y = -x^2, we can substitute the x-coordinates of the points into the function and check if the resulting y-coordinates match the given ones.

Let's start by checking each point individually.

1. Point A(1, -1): - Substituting x = 1 into the function y = -x^2 gives: - y = -(1)^2 - y = -1

- The resulting y-coordinate matches the given y-coordinate of A, so point A(1, -1) belongs to the graph of the function y = -x^2.
