Answer these questions for the poset ({2, 4, 6, 9, 12, 18, 27, 36, 48, 60, 72}, |). a) Find the maximal elements. b) Find the mi
nimal elements. c) Is there a greatest element? d) Is there a least element? e) Find all upper bounds of {2, 9}. f ) Find the least upper bound of {2, 9}, if it exists. g) Find all lower bounds of {60, 72}.
I'm fairly sure they want you to cross multiply then graph. This will give you 'zeroes' which are solutions for x if you graph (4x^3+3x^2)= z it'll give you a zero at -0.75 which means x= -3/4
