Question

vvvvv

Answer 1

@mathmate @MathMusician @RhondaSommer

Answer 2

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.

Answer 3

yes, thats what it is @mathmate

Answer 4

@mathmate hello??

Answer 5

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

Answer 6

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

Answer 7

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.

Answer 8

i need help with this specific one!!! I come to opensdtudy for help with THIS problem, not one like it!

Answer 9

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.

Answer 10

no, i don't want a direct answer i want to learn HOW to do THIS specific problem @Big_Mike_Lifting
