Which one of these has a parabola with a vertex at 1,-2

Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The vertex is the bottom of the curve
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
The equation
y = (x - 1)² - 2 has a vertex at (1, - 2) → A
