A satellite's signal strength follows S(d)=100d2+1S(d) = \frac{100}{d^2 + 1} where dd is distance in thousands of kilometers from the transmission point. Communication requires signal strength ≥ 4, but interference occurs when strength > 50. The satellite orbit restricts dd to the interval [0.5,8][0.5, 8]. What domain ensures reliable communication without interference?
