Question: Shilpa's gym membership includes a one-time fee of $20. She then pays a discounted fee of $5 for each visit. The function that shows her average cost after x visits is:f(x)=20+5x/xRecall the general form of a rational function:f(x)=(amx^m+...+a1x+a0)/(bnx^n+...+b1x+b0)Which statement defines the horizontal asymptote?

Question: 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 functionI=P/4pier^2where P is the power of the sound. Explain the behavior of the graph of I and what it means in context.

Answer: Check each that you included in your solution.The vertical asymptote is r = 0.The intensity is undefined at the source.The horizontal asymptote is I = 0.As the distance from the source increases, the intensity goes to zero.The intensity decreases as the distance increases.
