Functions and Transformations

Which parent function matches the graph?

• y = |x|

• y = x

• y = x²

Which equation below is a quadratic function translated left 4 units?

• y = x² + 4

• y = (x + 4)²

• y = (x - 4)²

• y = 4x²

Write the equation that results if the parent absolute value function is shifted right 15 units, down 3 units, and reflected vertically.

• reflected over x axis, stretched by 2, right 3, up 3

• reflected over x axis, stretched by 2, left 3 up 3.

• reflected over x axis, shrunk by 2, right 3, up 3

• reflected over the x axis, shrunk by 2, left 3, up 3

If you have a point G (-3, 2), what will G' be after the translation (x - 7, y + 3)?
