. In class, Michael and Kayla were working together on the following problem in class: \text { Find } \int x \sqrt[3]{3-2 x} d x ) Kayla says, “u should be (3 – 2x) because I always pick the most inside factor of a function as my u." i. Will Kayla's substitution work in this case? Explain your reasoning. ii. Does Kayla's idea work for all u-substitutions (if it does explain, if not give an example were it does not)? b) Michael says the u should be 3 – 2x because I always pick the most complicated factor of a function as my u. i. Will Michael's substitution work in this case? Explain your reasoning. ii. Does Michael's idea for all u-substitutions (if it does explain, if not give an example were it does not)?
