Unit 2 Transformations: Pretest

• The graph shows a reflection on the x- axis.
• The graph shows a reflection on the y-axis.
• The graph shows reflection across the x line.
• The graph shows reflection across the origin.

What is the image of D(4,7) if the translation is 3 units left, 4 units down?

• D'(1,3)
• D'(0,4)
• D'(7,11)
• D'(8,10)

If the vertices of a triangle are A(5,2), B(1,0), and C(1,6), what would the new points of a y-axis reflection?

• A'(-5,-2), B'(-1,0), and C'(-1,-6)
• A'(5,-2), B'(1,0), and C'(1,-6)
• A'(-5,2), B'(1,0), and C'(1,6)
• A'(-5,2), B'(-1,0), and C'(-1,6)

• The house has no lines of symmetry
• The house has one line of symmetry
• The house has two lines of symmetry
• The house has three lines of symmetry

• The figure has rotational symmetry
• The figure does NOT have rotational symmetry

If you are given the composite function
T(x,y)-->(x+3, y-2) o r(90 degrees)
What order would you perform the transformations?

• Translation then Rotation
• Rotation then Translation
• Order doesn't matter

If you were to draw an image in Quadrant 4, rotate the image 90 degrees counter clockwise, then reflect the image over the x-axis, what quadrant would the image be in?

• Quadrant 4
• Quadrant 3
• Quadrant 2
• Quadrant 1
