try factoring the denominator what values of x are not possible?
x=-1 and x=3
the domain is all possible values of x

so -1 and 3 are not in the domain
The 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.
oh so all reals except x=-1 and x=3 for the domain
ok thanks! but what about the range?
the range is all possible values of f(x)
so can you figure that out?
um how would i set it up?
dang ok.. don't solve it for me but how would i go about that?
well for a start the values of f(x) corresponding to x=3 or -1 will be excluded
Couldn't I find the inverse of the function and then find the domain?
yes the inverse of the function has domain which equals range of the function
ok thanks for your time and patience!
