When , the horizontal shift is described as: - The graph is shifted to the left units. - The graph is shifted to the right units.Horizontal Shift: NoneStep 6The vertical shift depends on the value of . When , the vertical shift is described as: - The graph is shifted up units. - The graph is shifted down units.Vertical Shift: Down UnitsStep 7The sign of describes the reflection across the x-axis. means the graph is reflected across the x-axis.Reflection about the x-axis: NoneStep 8The value of describes the vertical stretch or compression of the graph. is a vertical stretch (makes it narrower) is a vertical compression (makes it wider)Vertical Compression or Stretch: NoneStep 9To find the transformation, compare the two functions and check to see if there is a horizontal or vertical shift, reflection about the x-axis, and if there is a vertical stretch.Parent Function: Horizontal Shift: NoneVertical Shift: Down UnitsReflection about the x-axis: NoneVertical Compression or Stretch: NoneStep 10
