I set up a book friend group, group number: 9-7-7-5-0-7-5-8-9.

As a rule, there will be a question when you join the group.

So, ladies and gentlemen, please listen to the question:

…………

Given that the derivative of the function f(x) at x=1 is 3, the analytical expression of f(x) may be ()

A、f(x)=(x-1)²+3(x-1)

B、f(x)=2(x-1)

C、f(x)=2(x-1)²

D、f(x)=2(x²-x)

Enter the answer to this question to join the group.
