In a dilation what is preserved and what is altered?

Note that a dilation is not a rigid transformation, because it does not preserve distance. Dilations do, however, preserve angles. A shape and its image after a dilation will be similar, meaning they will be the same shape but not necessarily the same size.

Step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
