[3 Marks] (Multiple Choice Question) Consider the function f(I) = In(8 + 2723) f(x) it is decreasing on (- , 16 16 O 2, 00) with no local extrema and it is concave down on (0, 25 ) and concave up on (-?, 0) and (13/ 27, 00), with inflection points (0, In (8)) and ( 27 (27, In (24) ) f(I) it is increasing on (- 2,0) and decreasing on (0, oo) with a local maximum at (0, In (8)) and it is concave up on (0, 16 16 O 27 ) and concave down on (27, 00 ) with inflection point (3 16 27, In (24)) O f(z) it is increasing on (-? , 00) with no local extrema and it is concave down on (0, 16 16 7 ) and concave up on ( 271 00), with inflection point ( 16 27 , In (24) ) 8 f(I) it is increasing on (-?, 00) with no local extrema and it is concave up on (0, 16 27 and concave down on (-2, 0 8 0) and ( 16 271 00), with inflection points O (0, In (8)) and (1 27 16 , In (24) ) None of the above
