Answer: The reflection is: y' = -3x^2 + 4x - 1
Explanation:
We have the parabola y = 3x^2 - 4x + 1
When we do a reflection in one of the two principal axis (x-axis or y-axis), the thing we need to do is multiply the other variable by -1 (if the reflection is done in the x-axis, we multiply y by -1)
We have that our new graph is the graph of -1*y, and this is = -1*(3x^2 - 4x + 1)
The reflection is: y' = -3x^2 + 4x - 1
