Describe the Transformation
The parent function is the simplest form of the type of function given.
For a better explanation, assume that is and is .
The transformation from the first equation to the second one can be found by finding , , and for each equation.
Find , , and for .
Find , , and for .
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.
Vertical Shift: Down Units
The sign of describes the reflection across the x-axis. means the graph is reflected across the x-axis.
Reflection about the x-axis: None
To 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: Left Units
Vertical Shift: Down Units
Reflection about the x-axis: None
