it's easy to check x=0. That makes y>= 19/3
check the other points in like manner
the vertex is at (4,1) so y will be greater than 1 in all cases
The solution set of the inequality y(>/) 1/3(x-4)^2+1 includes the points
A. (–1, 1), (4, 0), and (7, –1)
B. (1, 3), (4, 1), and (8, 2)
C. (4, 2), (7, 4), and (8, 8)
D. (–4, 2), (0, 9), and (9, 1)
