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:

  1. Original point (1,5)(1, -5):

    • New x-coordinate: 14=31 - 4 = -3
    • New y-coordinate: 5+2=3-5 + 2 = -3
    • Translated point: (3,3)(-3, -3)
  2. Original point (3,7)(-3, 7):

    • New x-coordinate: 34=7-3 - 4 = -7
    • New y-coordinate: 7+2=97 + 2 = 9
    • Translated point: (7,9)(-7, 9)
  3. Original point (1,3)(-1, 3):

    • New x-coordinate: 14=5-1 - 4 = -5
    • New y-coordinate: 3+2=53 + 2 = 5
    • Translated point: (5,5)(-5, 5)

Translated Points (Range):

The resulting range after translation is (3,3)(-3, -3), (7,9)(-7, 9), and (5,5)(-5, 5).

Matching with Options:

The correct range from the options is (3,3),(7,9),(5,5)\boxed{(-3, -3), (-7, 9), (-5, 5)}, which is the 3rd option.

  2. How would a translation 3 units right and 5 units down affect the coordinates?
  3. What is the difference between a translation and a rotation in coordinate transformations?
  4. Can a translation change the orientation of a figure?

Tip: When translating points, always remember to adjust both the x and y coordinates accordingly, depending on the direction and magnitude of the translation.
