Aconvex mirror, like the passenger-side rearview mirror on a car, has a focal length of -2.2 m . an object is 4.4 m from the mirror.

The question is missing, but I guess the problem is asking for the location of the image.

We can solve the problem by using the mirror equation:

where
f is the focal length of the mirror
is the distance of the object from the mirror
is the distance of the image from the mirror

For a convex mirror, the focal length is taken as negative, so in our problem 
f=-2.2 m
The distance the object is


And if we use the previous equation, we can find the distance of the image from the mirror:

from which we find

where the negative sign means the image is virtual (located behind the mirror)
