Question

A transformation T : (x, y) (x + 3, y + 1). The preimage of the point (4, 3) is (-1, -2) (7, 4) (1, 2)

Answer 1

(1, 2)

Explanation:

'Undo' the rule on the image to get the pre-image.

`(4,3)\rightarrow(4-3,3-1)\rightarrow\boxed{(1,2)}`

(1,2) would be the pre-image to (4,3).

To see if it's correct:

`(1,2)\rightarrow(1+3,2+1)\rightarrow(4,3)`

(1,2) should be correct.
