Instantaneous rate y(x) = (5-x)^4 at x = 4

[bee77]

Instantaneous rate y(x) = (5-x)^4 at x = 4

can anyone please help me with this I'm not sure how to do it

I'm not sure what your "it" means.

"Instantaneous rate" refers to a function's derivative. In this exercise, they're asking for the value of function y's derivative when x = 4.

Use the Power Rule and the Chain Rule, to determine y'(x). Then evaluate y'(4).

If you need more guidance, please show what you tried. :cool:

They didn't cover this part of the textbook in class? Okay; try some online lessons, such as here. Please study at least two lessons from the list.

Once you have learned about the relationship between rates of change and derivatives, please attempt the exercise. If you get stuck, please reply with a clear listing of your efforts, starting with your derivative (as explained in the previous reply). Thank you!
