Answer:
D) 2(x - 3)² + 1
Step-by-step explanation:
First off:
the equations are in y = a(x-h)²+k format.
So, that means that since the vtx is (3, 1), the answers could only be c or d
The difference between the two is one parabola is reflected (negative) and the other is facing up. Since (1, 9) is above the vtx, only D is the one that passes through (1, 9) because it is the only one facing upward to touch that point.
