Transformations of Functions All Types

Which of the following describes a reflection over the x-axis?

• a

• h

• k

• x

Write an absolute value function given the following transformations: Reflection over the x-axis Translates left 2 units and 7 units up

• y = -|x + 2| - 7

• y = |x - 2| - 7

• y = -|x + 2| + 7

• y = -|x - 2| + 7

• None of these

Describe the transformation from the parent square root function:

• Vertical stretch

• Vertical compression

• Translation 5 units right

• Translation 5 units left

• Translates left 1 unit

• Vertical compression

• Translates down 1 unit

• Translates right 1 unit

• Vertical stretch

What kind of function is this?

• Linear

• Absolute Value

• Quadratic

• Exponential

• None of the above

• Translates right 2 units

• Vertical Stretch by 2

• Reflection over the y-axis

• Reflection over the x-axis

What type of function is this?

• linear

• quadratic

• square root

• absolute value

• None of these

A reflection

• Has a central point that stays fixed and everything else moves around that point

• a transformation that changes the size of a figure

• a transformation in which the preimage is flipped across a line

• a function that moves an object a certain distance. The object is not altered in any other way.
