thanks, can you help in finding a domain of a function?
Negation \neg \(\neg\) |dw:1348404218012:dw| \[\neg C\]
what is your function?
factorise the numerator and denominator
btw, "or" is like the union of the set and "and" is like the intersection of a set. Is that correct?
"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
what is the only number that dosent make sense in a denominator ? , what are two point values for x that would make your function undefined ?, exclude these from your domain
{x|x>2 and x>3 and x>=5 and x>=4} is this correct?
i get \[\{x|((x≠2)\wedge (x≠3))\}\]
hmm im not right though
The answer in my notebook says: dom K: {x|x<2 or 3=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
there is a strange discontinuity where 4
my notes also says that "use the number line to graph the values for which the function is defined.
that is for finding the domain.
well 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 ∞
