Chapter 14, Problem 14CR

To determine

Tofind: the inverse of $D_{O,4}$ .

Answer to Problem 14CR

The inverse of $D_{O,4}$ is $D_{O,\frac{1}{4}}$ .

Explanation of Solution

Given information:

The dilation us $D_{O,4}$ .

Calculation: since, $D_{O,4}$ gives the coordinates after multiply by $4$ .

So its inverse must be gives the coordinates multiply by $\frac{1}{4}$ .

Thus, the inverse is $D_{O,\frac{1}{4}}$ .
