Question

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

Answer 1

A

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

Answer 2

y = (x-1)^2 - 2

Explanation:

The vertex is the bottom of the curve
