@Mertsj or @phi can you guys help?
well the domain are the x values for which the function is defined. for a fraction such as yours to be undefined the divisor must be 0 but x^2+8 > 0 for every x so the domain is R, every real number
Remember, the denominator cannot be 0. Since the denominator is x^2+8, and x^2 has a smallest value of 0, and 0+8 will always be positive, there are no restrictions on x and the domain is all real numbers.

hey Mertsj, can you help me with some advanced number theory? i am trying to do something with the sigma function(sum of divisors of number)
so then the domain would be all real numbers greater than 0?
yes
dag nabit it was just all real numbers :/ thanks anyways
Didn't I post that the domain is all real numbers?
