Which statement is true? a dilation is a function because every point on the pre-image corresponds to exactly one point on the image. a dilation is a function because the scale factor is always greater than 1. a dilation is not a function because a point on the pre-image could be mapped to more than one point on the image. a dilation is not a function because the image is not congruent to the pre-image.

A dilation is a function because the scale factor is always greater than 1.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
