Question 3 6 points How Did I Do? Find the fourth derivative of f (x) = 2x + ln (x) 144x. Enclose arguments of functions in parentheses. For example, sin (2x). (4) (x) = = a b 20 |a| 8 8 sin (a) 5 Question 4 6 points How Did I Do? Find the 40th derivative of f (x) = sin3x. Enclose arguments of functions in parentheses. For example, sin (2x). Enter your answer using exponents for constants. For instance, write 36 instead of 729 (hint: your constant will likely be larger than this). (40) (x) = a b a a sin (a)
