the choices:
all real numbers except -(c/d)
all real numbers except -1
all real numbers except -(d/c)
all real numbers except (c/d)

at x = infinity, f(x) = a/c
at x = -infinity, f(x) = a/c
at x = -d/c, f(x) = +/- infinity
at x = -b/a, f(x) = 0
vertical asymptote at -d/c
horizontal asymptote at -b/a
so the domain of f(x) is -infinity to +infinity except -d/c

The domain is all x such that x is not equal to -d/c. You know this because your function is not defined for any value of x that would make the denominator of the fraction in the function zero (division by zero is not allowed).

not absolutely sure... but domain is the x coordinate. so solve the equation for x

easy
