Answer:
B
Step-by-step explanation:
Function transformations are easy to do when you remember four rules:
- adding or subtracting in the function moves it left and right
- adding or subtracting outside the function moves it up or down
- multiplying and dividing to the function stretches or compresses it
Here the 2 is being multiplied to the function which vertically stretches the function.

The new graph is

Since there is no change for x, there is no horizontal shift.
BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.
Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2
Option a is right
i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
