Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by the functionwhere P is the power of the sound. Explain the behavior of the graph of I and what it means in context.

Check each that you included in your solution.

because

The graph approaches 0 as x approaches infinity.The graph approaches 0 as x approaches negative infinity.The graph approaches 2/3 as x approaches infinity.The graph approaches –1 as x approaches negative infinity.

The horizontal asymptote cannot be determinedX is x = 0is x = c✔ is y = 0is y = c.

The domain X cannot be determined✔ is all nonzero real numbersis all real numbers except cis all real numbers.

The range cannot be determined✔ is all nonzero real numbersis all real numbers except cis all real numbers.
