How do we draw the image formed

yeah sure

Explanation:

well its s mirror so Ray's are reflected right?

so 1 draw a line passing through the focus ,extend it to hit the mirror, so a reflection occur which is drawn parallel to the principal axis

2 draw a line parallel to the principal axis, extend it to touch the mirror and the a reflection occur which is a line drawn passing through the focus

3 draw a line passing through the centre of curvature, extend it to touch the mirror and the reflection ofcourse passes the same line at first so no need to indicate its reflection

now the point where two line meets is the image

i believe it is b. what was the cause of the big bang

hope this !
