Question

The parabola below is a graph of the equation, . -y^2+x=-4

Answer 1

The parabola divises the plan into 2 parts. Part 1 composes the point A, part 2 composes the points C, D, F.
+ All the points (x;y) satisfies: -y^2+x=-4 is on the parabola.
+ All the points (x;y) satisfies: -y^2+x< -4 is in part 1.
+ All the points (x;y) satisfies: -y^2+x> -4 is in part 2.

And for the question: "Which of the points satisfy the inequality, -y^2+x<-4"
we have the answer: A and E
