The composition of functions for the given sequence of transformations is (x, y) = (x + 4, -y - 5)
What is the composition of functions for the given sequence of transformations?
From the question, we have the following parameters that can be used in our computation:
- Reflection over the y -axis
- Rotation by 180° counterclockwise about the origin
- Translation down 5 units and right 4 units
The rule of reflection over the y -axis is
(x, y) = (-x, y)
The rule of rotation by 180° counterclockwise about the origin is
(x, y) = (-x, -y)
So, we have
(x, y) = (x, -y)
The rule of translation down 5 units and right 4 units is
(x, y) = (x + 4, y - 5)
So, we have
(x, y) = (x + 4, -y - 5)
Hence, the composition of functions is (x, y) = (x + 4, -y - 5)
