Answer
The image is inverted, because the magnification m is negative.
Work Step by Step
The magnification is negative, and because of equation 23-3, we see that $d_{i} \gt 0$. Now we know that the image is real and in front of the mirror (i.e., on the same side of the mirror as the object).
The mirror is concave, because convex mirrors can only form virtual images from a real object.
