**calculus**

ok. this question also had a part a) which was (a) What is f '(3)? so i just divided (9h^2+8h)/h (h(9h+8))/h and plugged in 0 since lim->0 got 8 as my answer. now for B) i tried plugging 3 into (h) in func 9h^2+8h/h did same with 7 and got wrong answer. i tried many ...

**Math **

Use the limit definition of the derivative to find f′(x) if 1. f(x) = x^2 + 3x 2. f(x) = 1/x + 1 kk for number one i got f'(x) = 2x+3 and for number two i got f'(x) = -1/(x+1)(x+1) can any one verify these, especially number 2.
