The vertex of a parabola is (3,2). a second point on the parabola is (1,5).which of the following points is also on the graph? a.(3,-2) b. (3,7) c. (-1,5) d. (5,5)

+ The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)²+2
+ A second point on the parabola is (1,5) and we replace x=1 and y=5. We have: 
5=a(1-3)²+2  ,  so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)²+2

And by checking we have the point (5;5) is on the parabola
