how to solve using limit definition of the derivative for f(x)=2x^3+5x^2-7x-4
my ans:
6x^2+10x-7
plse correct me...
Well you have to show your work probably and you do so by going through the grunt work of expanding and simplifying in order to evaluate the limit:
Eventually you can factor out an h from the top to cancel it with the bottom and you should get your answer. Like I said, a lot of grunt work.
