Set up the difference quotient (do not simplify), lim x - a 7 b. The numerator of the difference quotient when simplified into a single fraction becomes 4ax + 2x + 2a + 1 X 7 c. Before taking the limit, and after simplifying, the difference quotient expression becomes lim 4ax + 2x + 2a + 1 X x - a 7 d. Taking the limit, we have that f'(a) = (2a + 1 ) 2 Submit Answer1.
