Solution

Step 1: Given data and figure:
We know when the object is between focus and curvature image formed in real, inverted and magnified.
$\Rightarrow$ The spherical mirror used is a concave mirror
From the above diagram, we can see the focus is between the object and the pole
Hence,
1. Spherical mirror used is a concave mirror
2. Focus is between object and pole
