First principle (1 Viewer)

[Smile12345]

Hello...

Could someone please see if I'm on the right track for the below question?

Q. ,show that f'(0) = 3 by using first principle.



Now, not sure...

Hopefully it looks ok. Still practicing Latex.

Thanks for your help in advance.

that should be 3(x+h) there. but otherwise the rest is right, and remember that the lim h ->0 should still be there until you substitute h=0 in.

Thanks... Yeah ok... The 3(x + h) needs to be in the middle line?
