Use the thin lense equation. 1/f = 1/d + 1/o, where f is the focal length, d is the image distance, and o is the object distance.
The focal length of the lens and the distance between the lens and the object.
Yes, but it will not be clearly resolved because it is not at the focal length. The same could be said for the image just outside the focal length. The further from the focal length the attempt is made to resolve the image, the poorer the resolution will become.
The focal point. It can affect size, real/virtual, inverted/upright.
The object and image distance are interchangeable, because this gives rise to points of conjunction, a point on an object has a conjugate point on the image, both will yield the same value for f and it is a property of optical systems known as reversibility.

Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
1/object distance + 1/ image distance = 1/focal length
Focal Length
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
the focal length of the eye lens is adjusted so that the image distance does not change.
Easy way: Use it to form an image of the sun or moon, and measure the distance of the image behind the lens. When the object is at infinity, the distance between the lens and the image is the focal length of the lens.
1/(focal length) = 1/(distance of object) + 1/(distance of image) is the formula for calculating x of a lens knowing only the focal length which is the distance from the lens to the image of sun formed by it.
The image is formed behind the lens at a distance equal to the focal length. If the distance to the object is D1 and the focal length is F, then the distance D2 to the image is given by this equation: 1/D2 = 1/F - 1/D1
Here's the equation you want. It's called the "Lensmaker's Formula".1/i + 1/o = 1/fi = image distance from the lenso = object distance from the lensf = focal length of the lens
When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
