Math help please!!!?

The domain of a function is D: [-3,0) U [4,5)U (5, Infinity) Determine if each of the following values are in the domain
a.-3
b.0
d.4
e.5
f.10

or:The domain of a function is D: [-3,0) U [4,5)U (5, Infinity) Determine if each of the following values are in the domain a.-3b.0d.4e.5f.10

or:a,d,f are in this domain. (Also you're missing a c option there.)Explaination/Theory.D1: (-3,0) means that the numbers between -3 and 0 are included in the domain.But also observe this.D2: [-3,0) not only means that the numbers between -3 and 0 are included in the domain but also -3 is included in this domain.D3: [4,5) All numbers between 4 and 5 are included in this domain. 4 is also included in this domain because of this \"[\" symbol.5 is not included in this domain because of this \")\" symbol.When detecting domains of different functions, infinity has always a \")\" or \"(\" next to it. ALWAYS.D4:(5,+infinity) means that ALL NUMBERS above 5 are included in this domain. BUT NOT 5.So 5,432427834284837 is included in this domain, along with 10, 325852, 412482484, 999999999999999 etc.BE CAREFUL.Now let's return to our domain, D:[-3,0) U [4,5)U (5,+Infinity)Are 1,2,3 included in this domain? There're not.Neither is 0,53252 or 3,064.Because our domain says so:We want the number -3 and the numbers between -3 and 0. But not 0. Also the number 4 and the numbers between 4 and 5. But not 5. Last, ALL the numbers above 5.So ],[ is included.),( is NOT included.Infinity has ),( but it's side ALWAYS, whether it is \"(-infinity\" or \"+infinity)\".U \"unifies\" smaller domains together.{Number}: },{ are used if you want to included only one number in your domain, that is not already included! I advise you ask your teacher whether you will use this or not.Sorry, if any of these terms are incorrect, I'm greek. But the theory is correct.
