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

Option 2nd is correct that is

Step-by-step explanation:

We have given  the vertices of a parabola

General equation of parabola is:

Here, (h,k) is vertex of the parabola

Here, h=1  and k=2 and a=1

On substituting the values in the general equation of the parabola we get:

Therefore, option 2nd is correct.

1. 34

2. 268

3. x=14.4
