does the domain of [tex]f(x) = \sqrt {x-1}[/tex] equal [tex]dom(f) = (1,\infty)[/tex]? if wrong, can you tell me what i did wrong? thanks.
Your book is very sloppy in asking this (along with most other books).Gecko said:the question was exactly "What is the domain of [tex]f(x) = \sqrt {x-1}[/tex]?" so the answer is [tex]dom(f) = [1, \infty) [/tex]?
Gecko said:does [x,y) mean the the domain can be equal to or greater than x and greater than y, or is it less than y? and (x,y) means that its greater than x and y or just less than y? i was confused with this in the book as well (wish the answers where in the back >.<)
