Use a mapping diagram to determine whether the relation is a function. {(2,3), (5,5), (5,9), (8,8), (1,14), (2,1)}

The relation is not a function

no it is not a function

Step-by-step explanation:

A geometry transformation is either rigid or non-rigid; another word for a rigid transformation is "isometry". An isometry, such as a rotation, translation, or reflection, does not change the size or shape of the figure. A dilation is not an isometry since it either shrinks or enlarges a figure.
 The answer is B. or A dilation changes the dimensions of a figure, while an isometric transformation preserves dimensions.
