Which ordered pair is a solution to the graphed inequality?
1 answer:
Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:
From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.

1. The intevals of x should be:
because point (-1,1) lies on the linear part of the graph;
because the point (-1,1) doesn't lie on the first parabola;
This gives you that option B is false.
Now the middle part of the graph is parabola going in negative y-direction and right part of the graph is parabola going in positive y-direction. Therefore, option A is false, because there the middle parabola is going upward.
The third part of the graph has vertex at point (5,4). In option D the vertex of the parabola is (3,4), so this option is false.
Answer: correct choice is C.
