Given f(x) = √x²-1 which one of the following steps, not in correct order, showing the calculation of f'(2) is INCORRECT? \) O A. D. O B. f'(2) = 1/3 O C. O E. h+4 h→0 √h² +4h+3+√3 O F. f'(2) = lim ƒ(2+h)-f(2) h √h² + 2h+3-√3 h - √(2 + h)² − 1 − √√3 h h² + 4h h→0 h(√h² +4h+3+ √√3) f'(2) = lim h→0 f'(2) = lim h→0 f'(2) = lim h→0 f'(2) = lim​
