2X+ 1 X4. 5 a. Set up the difference quotient (do not Simplify), lim X a b. The numerator of the difference quotient when Simplified into a single fraction becomes :2. Before taking the limit, and after simplifying, the difference quotient expression becomes lim X a cl. Taking the limit, we have that f'(a) = Submit Answer 3.
