Which of the following equations is of a parabola with a vertex at (1, -2)?

Question

A.)y = (x - 1)2- 2

B.)y = (x - 1)2+ 2

C.)y = (x + 1)2- 2 D

.)y = (x + 1)2+ 2

Answer 1

Vertex is on the parabola.

y = (x - 1)^2- 2

Substitute (1,-2) is in above equation

-2=(1-1)^2-2

--2=-2

Therefore option (A) is correct
