The parabola below is a graph of the equation, -y^2+x=-4. which of the points satisfy the inequality. ( points a-f )

Test the value (x,y) of each point in the equation-y^2 + x <= -4   BY 
1) because the equation has = so every point in the equation  -y^2 + x = -4 is applied   this case is B ... satisfy  2) A, E is in the same area choose one to test test A(-4,2) :   -(2)^2 + (-4) <= -4  which is true the A and E is satisfy the inequality   3) no need to test fo C, D, F on the different area they are not satisfy.  but you can guess it will satisfy -y^2 + x > -4
