Step-by-step explanation:
2. 3. 5. are correct
1. and 4. are actually interchanged
The rate of change is simply the derivative of a function with respect to the other variable. In this case the rate of change with respect to x is desired. Therefore
f(x) = x^3 - 3x^2
f'(x) = 3x^2 - 6x
therefore the rate of change of y with respect to x is dy/dx = 3x^2 - 6x
This question doesn't make any sense please reword and i will do my best to solve.
