Proving that a set is non-empty and bounded above. A isn’t empty because: -1.5 is in the set. Consider 1^2 + 3*1 + 2 = 6, so clearly 1 isn’t in A. Polynomials are continuous functions so 1 then either has to be an upper or lower bound. Since -1.5 is in the set 1 must be an upper bound. Let f(x) = x^2 + 3x + 2, Let b...
