Answer 1

Mirror formula : 1/f = 1/v + 1/u

Focal length, f of a mirror does not change in any condition.

Answer 2

Heya!

Mirror Formula:

1/f = 1/v+1/u.

f does not change when object distance u from the mirror is changed,this is because the focal length of the mirror depends upon the curvature of the mirror.
