anonymous · Answer

can you help ?

afrodiddle · Answer

This is a rational function f(x) = 7/x-a

anonymous · Answer

thats all?

afrodiddle · Answer

I gave you an example.
Make your own
fill in the blanks :P

$$f(x) = \frac{ blank }{ x-a }$$

anonymous · Answer

am i supposed to plug in numbers for a?

afrodiddle · Answer

Does it state so? then yes.

afrodiddle · Answer

the domain is all real numbers except a

anonymous · Answer

so i can have f(x)= 5/x-a?

afrodiddle · Answer

Yes.

afrodiddle · Answer

( - ∞ , a ) U ( a , + ∞ )
is the interval notation of a domain.

anonymous · Answer

and how can i get the interval and set notation?

afrodiddle · Answer

{ x ϵ ℝ | x ≠ a } 
Is the set notation.

afrodiddle · Answer

as I said, the domain is all real numbers except a.
