OpenStudy (mathmate):

Is it \(\Large f(x)=\frac{13}{10-x}\)? Hint: All rational functions have R (all rational numbers) as the domain, \(except\) points where the denominator becomes zero.

OpenStudy (iwanttogotostanford):

yes, thats what it is @mathmate

OpenStudy (iwanttogotostanford):

@mathmate hello??

OpenStudy (mathmate):

@iwanttogotostanford Please read my last post, including the last paragraph! :)

OpenStudy (iwanttogotostanford):

i did ! I still need help though .. @mathmate

OpenStudy (mathmate):

Example: Find domain of \(\Large f(x)=\frac{x}{2-x}\). Denominator is (2-x), so when x=2, denominator is zero. For a rational function, domain is all real except when denominator is zero, so Domain=\((-inf,2)\cup(2,+\inf)\), or simply R\2 meaning all real except x=2.

Basically, he's wanting the direct answer. It's apparently frowned upon to be given the direct answer to a question, but I feel that if you give them the answer, if they're interested in learning in the first place, they can solve the problems backwards, to figure out how the answer was correct.
