here object distance is at infinity
focal length is -10cm
by using mirror formula
1/f = 1/v + 1/u
1/-10 = 1/v + 1/infinity
1/-10 = 1/v + 0
so v = -10 cm
position of image is that the image is formed 10 cm to the left side of the mirror
nature of image is real , inverted and diminished
for ray diagram , refer ncert textbook for concave mirror of object position at infinity and image position at focus.
