Representing and Comparing Transformations

If a figure undergoes a translation that moves it 6 units right and 4 units down, which vector represents this translation?

How did we transform from y=x²

y = -3x²

• vertical reflection and vertical shift down

• vertical reflection and vertical stretch

• horizontal stretch

• vertical reflection and vertical compression

What is the rule that describes the translation that maps ∆LMN to ∆L'M'N'?

• 3 units right and 4 units up

• 3 units left and 4 units up

• 3 units right and 4 units down

• 3 units left and 4 units down

C(-6, 2) and B(-1, -1)
Translate (x, y) -> (x + 3, y - 1)

• C' (-3, 1), B' (2, -2)

• C' (3, -1), B' (-2, -4)

• C' (-9, 1), B' (-4, -2)

• C' (-7, 1), B' (-2, -2)

Does the image show a dilation centered at the origin? If yes, did the image enlarge, reduce or none of the above...and by what scale factor?

• Yes, it is an enlargement with a scale factor of 2

• Yes, it is a reduction with a scale factor of 1/2

• No, it is not a dilation

• No, it is not centered at the origin

How did we transform from the parent function?

g(x) = -1/5(x - 1)² + 7

• reflection, vertical shrink, horizontal right, vertical up

• vertical shrink, horizontal shift left, vertical shift up

• reflection, horizontal shift right, vertical shift down

• no changes were made to y = x²

Triangle ABC is going to be translated. How is ABC being translated if the rule (x,y) --> (x+3, y-2) is used?

• 3 up and 2 left

• 3 right and 2 down

• 3 left and 2 up

• 3 right and 2 up 

How would you describe the following translation verbally?

• 13 right

  7 down

• 12 left

  7 up

• 12 right

  7 down

• 13 left

  7 up

• reflection

• stretch

• shrink

• left 5, up 10

• right 5, up 10

Determine how to translate triangle ABC to triangle A'B'C'.

• (x-2, y+5)

• (x+2, y-9)

• (x-2, y+9)

• (x-9, y+2)
