Prove that set A={x∈R:x11+7x5+5–√x3+8x−2(cosx)<0}A={x∈R:x11+7x5+5x3+8x−2(cosx)<0} is non-empty and bounded above. Thus, by the completeness axiom, the supremum supAsupA exists as a real number.

2. f(x) = (x + 3)(x − 1)(x − 4)
Step-by-step explanation:
The roots of this polynomial graph are the x-intercepts.
These are x=-3, x=1, x=4
These implies that the factors of the function are:
(x+3), (x-1), and (x-4)
The factored form is given as:
Therefore the second option is correct.
