​

Answer 1

Answer:

The sign of the magnification tells us the orientation of the image.and its zoom level used to see stuff more clearly .If the sign is positive, then the image is upright. If the sign is negative, then the image is upside-down. In the examples above, we can see that amount by which an object will be magnified changes depending on its distance from the focal point.
