Question

Let f: R R be defined by f(x) = 3x - 2, find f'(x) and hence find '0), f'(1) and f'(2).​

Answer 1

Step-by-step explanation:

please mark as brainiliest answer I request you

Answer 2

Answer:

f(x)=3x=2.... [ Given ]

⇒  f(f(x))=f(3x+2)

                    =[3(3x+2)+2]

                    =9x+6+2

                    =9x+8

∴  f(f(x))=9x+8
