What transformation is happening?

f(x, y) ----> (x + 2, y - 3)

• slide up 2, left 3

• slide right 2, up 3

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

What is the Function Notation for this Reflection?

• f(x, y) → (y, x)

• f(x, y) → (-x, y)

• f(x, y) → (-y, -x)

• f(x, y) → (x, -y)

Which function notation can be used to represent the transformation

• f(x, y) → (y, x)

• f(x, y) → (-x, y)

• f(x, y) → (-y, -x)

• f(x, y) → (x, -y)

• (-4, 2)
• (4, -2)
• (2, 4)
• (-2, 4)

Describe the transformation shown in the graph.

• Reflect over x-axis
• Reflect over y-axis
• Rotate 90 degrees CCW
• Rotate 270 degrees CCW

A triangle has vertices with coordinates (2,0), (3, -1) and (-2,-5). If the triangle is dilated by a scale factor of 3 with the origin as the center of dilation, what are the coordinates of the vertices of the image?
