In mathematics, particularly in the context of functions, a pre-image refers to the set of all inputs (or arguments) that map to a specific output under a given function. For a function ( f: X \to Y ) and an element ( y \in Y ), the pre-image of ( y ) is the set ( f^{-1}(y) = { x \in X \mid f(x) = y } ). Essentially, it identifies which elements from the domain correspond to a particular value in the codomain.
The image and pre-image are congruent.

When a pre-image undergoes a translation, each coordinate of the pre-image is adjusted by adding a fixed value, known as the translation vector. This means that every point of the pre-image moves the same distance and direction, resulting in a new set of coordinates for the image. The relative positions of the points remain unchanged, preserving the shape and size of the figure. For example, if a point (x, y) is translated by (a, b), its new coordinates will be (x + a, y + b).
It means that the pre-image and image are on opposite sides of the centre of magnification.
You need information about a pre-image AND and image to work out a scale factor.
a pre-image is an image before and image is an image after
The image and pre-image are congruent.
Yes, it is.
isometry
Dilation - the image created is not congruent to the pre-image
The image and pre-image are congruent.
true.
Positive would be more magnification, and negative would be less magnification. * * * * * No. M > 1 indicates that the image is bigger than the pre-image (and on the same side of the centre of magnification); 0 < M < 1 indicates that the image is smaller than the pre-image (and on the same side of the centre of magnification); -1 < M < 0 indicates that the image is smaller than the pre-image (and on the opposite side of the centre of magnification); M < -1 indicates that the image is larger than the pre-image (and on the opposite side of the centre of magnification). M = 0 means the image is point-sized and at the centre of magnification. M = 1 means the image coincides with the pre-image. M = -1 means that the image is the same size as the pre-image and on the opposite side.

a reflection
That the image has moved in the same direction and distance of its outline
In general you don't. You can convert an image into ASCII art using tools like the PNM suite, if that's what you mean; then you just need to stick <pre> </pre> tags around the converted image.
