Math Problem Statement
A figure is translated 4 units left and 2 units up. If the domain (or pre-image) of the coordinate transformation (1, -5), (−3, 7), (−1, 3), what is the range (or image)?
pick one:
(-3, -7), (-7, 5), (-5, 5)
(5, -3), (1, 9), (3, 5)
(-3, -3), (-7, 9), (-5, 5)
(3, 7), (-7, 9), (-5, 5)
Solution
To determine the range (or image) after translating the given points, we apply the translation to each of the coordinates. The translation is defined as 4 units left and 2 units up.
Translation Steps:
- 4 units left: Subtract 4 from the x-coordinate.
- 2 units up: Add 2 to the y-coordinate.
Let's apply this to each point in the domain:
-
Original point :
- New x-coordinate:
- New y-coordinate:
- Translated point:
-
Original point :
- New x-coordinate:
- New y-coordinate:
- Translated point:
-
Original point :
- New x-coordinate:
- New y-coordinate:
- Translated point:
Translated Points (Range):
The resulting range after translation is , , and .
Matching with Options:
The correct range from the options is , which is the 3rd option.
