Ответ:
Simply place the f(x) polynomial over g(x) to get the f(x) / g(x) result. Since polynomials have an infinite domain, the only gap you will get comes from the denominator equaling zero. That happens when:
X - 1 = 0
+1 +1
X = 1
So the domain is: D: X≠ 1

Here's what I think I know:
1) the Voltage and the Resistance
2) Watts = Amps x Volts
so: 6 watts = A x 12, A = 0.5
Volts = Amps x Resistance
12 = 0.5 x R
R = 24 ohms
3) From step 2, A = 0.5 amps
4) since this is a series circuit, Re = Rh + 24
