Mathematics
1 answer:
Yanka [14]3 years ago
4 0

Answer:

A

Step-by-step explanation:

At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1)  part. This happens for x=1. So you can already rule out answers C and D.

Now fill in x=-2 in both remaining answers and see what happens.

For A: y = -2(-2 - 1)² + 3 = -15

For B: y = (-2 - 1)² + 3 = 12

That eliminates B and leaves A.
