Best ResponseYou've already chosen the best response.1try factoring the denominator what values of x are not possible?

Best ResponseYou've already chosen the best response.1the domain is all possible values of x

Best ResponseYou've already chosen the best response.1so 1 and 3 are not in the domain

Best ResponseYou've already chosen the best response.0The domain is the values that x can have. y = 2/(x^2  2x  3) has a denominator. Since division by zero is not allowed, you need to find which values of x would make the denominator zero. To do that, solve (which you did) x^2  2x  3 = 0 (x  3)(x + 1) = 0 x = 3 or x = 1 These are the value of x that must be excluded from the domain, so the domain is all real numbers except x = 3 and x = 1.

Best ResponseYou've already chosen the best response.0oh so all reals except x=1 and x=3 for the domain

Best ResponseYou've already chosen the best response.0dang ok.. don't solve it for me but how would i go about that?

Best ResponseYou've already chosen the best response.1well for a start the values of f(x) corresponding to x=3 or 1 will be excluded

Best ResponseYou've already chosen the best response.0Couldn't I find the inverse of the function and then find the domain?

Best ResponseYou've already chosen the best response.1yes the inverse of the function has domain which equals range of the function
