Please help me out with these!

3. Let f(iL') = ln(3:1: 3:3). Find number(s) :1: in the domain of f for which the tangem line is horizontal: i.e. f'(3:) = 0. 11:3 3:2 + l 4. Let f(11?) 111 (m) . Apply Law of Logarithms to simplify f (11:) into a sum or difference of simpler log- arithms. Then Find f'(;1:). 5. Let f(3:) = :53 33:2 93: + 7. (a) Find all critical numbers of f. (1)) Find intervals where f is increasing or decreasing
