Best ResponseYou've already chosen the best response.0well 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

Best ResponseYou've already chosen the best response.1Remember, 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.
