Confused about the formula
(1/-f)= (1/do)+(1/-di)
For locating an image for a convex mirror.
A rose is placed 15cm in front of a convex mirror of focal length 10cm. Determine the location of the image using the mirror equation.
(1/-10)=(1/15)+(1/-di)
-0.1=0.067 + (1/-di)
-0.166=(1/-di)
-di=(1/-0.167)
-di=-9.5941
di=9.5941
Am I on the right track there? I feel like I must be wrong bc that places the image before the focal point...
Thanks a bunch :)

draw a ray diagram to confirm your work.
I am & I can't get it to match up... They haven't given an exact height, they just say "at least 4 squares high" but between 4 squares & my cap I can't get it to that point.
