Learn to use the lens (and mirror) equation:
1/Do + 1/Di = 1/f
The object distance is Do = 17.0 cm in your case.
The focal length is 23.2 cm in this case.
Solve for image distance Di
The magnification is Di/Do
(note absolute value signs.
Di will be negative in this case. That means the image is virtual, and not inverted.
