Best ResponseYou've already chosen the best response.0btw, "or" is like the union of the set and "and" is like the intersection of a set. Is that correct?

Best ResponseYou've already chosen the best response.5"or" is like union "and" is like intersection kinda but they are used for slightly different things, i think the logic symbols are used for points, where as the set symbols are used for sets of points

Best ResponseYou've already chosen the best response.0The answer in my notebook says: dom K: {xx<2 or 3<x<=4 or x>=5} I only copied that from my classmate because I was absent when my teacher discussed this. so I don't know how they got that

Best ResponseYou've already chosen the best response.0my notes also says that "use the number line to graph the values for which the function is defined.

Best ResponseYou've already chosen the best response.0that is for finding the domain.

Best ResponseYou've already chosen the best response.5well x is defined from ∞ to 2 , at 2 this is a discontinuity, the from 2 to 4 defined, then discontinuity from 4 to 5 then defined again from 5 to ∞
