We start by restating the problem in our own words and listing the given candidate decompositions to evaluate each one.
Question restatement: Given (f ∘ g)(t) = sec(3 t^4) tan(9 t^8), determine which pairs (f, g) listed could realize this composition, where each option presents a candidate f(t) and a candidate g(t).
Option 1: f(t) = sec(t) tan(t), g(t) = 9 t/8.
- If we plug g(t) into f, we would get f(g(t)) = sec(9t/8) tan(9t/8). This is not equal to sec(3 t^4......Login to view full explanation登录即可查看完整答案
