For the function, find the following. f(x) = X+ 13 8x Exercise (a) f" (x) Step 1 While our function is a quotient, and thus the Quotient Rule would give us the derivatives we need, the calculations are simpler if we first rewrite the function as the sum of two fractions and then simplify. X + 13 X 13 + 13 + 8x 8x X 8x 8x Submit Skip (you cannot come back)
