Question 1090360: Which one of the following does NOT find the value of f'(5) for f(x) = 3x^2 – 2x – 4?
A.) All of these find the value for f'(5).
B.) f prime of 5 equals the limit as h approaches 0 of the quotient of the quantity 3 times the square of the quantity 5 plus h minus 2 times the quantity 5 plus h minus 4 minus 3 times 5 squared plus 2 times 5 plus 4, and h
C.) f prime of 5 equals the limit as x approaches 5 of the quotient of 3 times x squared minus 2 times x minus 4 minus 61, and the quantity x minus 5
D.) limit as h approaches zero of 3 times the quantity five plus h squared minus two times the quantity five plus h minus four minus the quantity three times five squared minus two times five minus four all divided by h.
My answer is A but I'd like confirmation that this is the correct choice, along with an explanation if applicable.

The definition of the derivative is,
df%2Fdx=lim%28h-%3E0%2C%28f%285%2Bh%29-f%285%29%29%2Fh%29%29
