Question: Being given the function f (x) =1/(3x+1),

a) By using the definition of the derived function (and not the rules of derivation), determine f' (x).

b) Determine the slope of the tangent to the curve of f (x) at the point (1, f (1)).

Instructions: You must use Maple 12 and show your calculations.
