SOLUTION:
Case: Transformation:
To find the transformation, compare the equation to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Method:
1,
[tex]y=(5x)^3-3[/tex]
Transformation features:
Horizontal: None
Shift: None
Stretch/Compression: None
Vertical:
Shift: Down by 3 units
Stretch/Compression: Stretch by a factor of 5
2.
[tex]y=-7(x+9)^2[/tex]
Transformation features:
Horizontal:
Shift: left by 9 units
Stretch/Compression: None
Vertical:
Shift: None
Stretch/Compression: Stretches by a factor of 7.
Final answer:
1.
Vertical:
Shift: Down by 3 units
Stretch/Compression: Stretch by a factor of 5.
2.
Horizontal:
Shift: left by 9 units
Vertical:
Stretch/Compression: Stretches by a factor of 7.
