Answer:
a vertical compression by a factor of , translated 4 units left, and a downward shift of 8 units.
Step-by-step explanation:
The transformed parabola has equation:
The parent function is the parabola with the vertex at the origin, which is
The addition of 4 within the parenthesis means there is a shift 4 units to the left.
The subtraction of 8 means a downward shift of 8 units.
The multiplier of half means a vertical compression.
Therefore the transformations are a vertical compression of , translated 4 units left, and a downward shift of 8 units.
