Question

If the domain is (0, 3), (4, 5), (-2, 8) and the range is (0, 9), (12, 15), (-6, 24), what is the coordinate transformation?

Answer 1

Notice that:

`\begin{gathered} (0,9)=(3*0,3*3), \\ (12,15)=(3*4,3*5), \\ (-6,24)=(3*-2,3*8). \end{gathered}`

Therefore the given transformation transforms the point (x,y) as follows:

`(x,y)=(3x,3y).`

Answer:

`T(x,y)=(3x,3y).`
