The parent function is the simplest form of the type of function given.

The transformation being described is from to .

The horizontal shift depends on the value of . The horizontal shift is described as:

– The graph is shifted to the left units.

– The graph is shifted to the right units.

Horizontal Shift: Left Units

The vertical shift depends on the value of . The vertical shift is described as:

– The graph is shifted up units.

– The graph is shifted down units.

In this case, which means that the graph is not shifted up or down.

Vertical Shift: None

The graph is reflected about the x-axis when .

Reflection about the x-axis: None

The graph is reflected about the y-axis when .

Reflection about the y-axis: None

Compressing and stretching depends on the value of .

When is greater than : Vertically stretched

When is between and : Vertically compressed

Vertical Compression or Stretch: Stretched

Compare and list the transformations.
