nis question we prove that certain sets are not convex. each of the following sets, give the coordinates of two points where P and Q are in the set, but the line from P to Q goes example, if the points are (1,2) and (3, 4), enter in the format (1,2).(3,4) R-{(s.):2+u221,y<아} 1,-1/2).(1,-1/2) s- {(r,9) : (2 – 1)² + y² < 10}u{(z,y) : (z+3)2 +y? < 18} T-{(2,p) : 2 > 6}n{(=,p) : ² < 4} (sqrt(-6),-2).(sqrt(6),2)

In this question we prove that certain sets are not convex. For each of the following sets, give the coordinates of two points where P and Q are in the set, but the line from P to Q goes outside the set. For example, if the points are (1,2)and (3,4), enter in the format (1,2),(3,4)
