The function that represents the average cost per person, including transportation, to a museum is y= 25+8x/x which statement is true about the graph of the function? the horizontal asymptote y = 0 means the cost approaches zero as the number of people increases. the horizontal asymptote y = 8 means the average cost approaches $8 as the number of people increases. the vertical asymptote x = 0 means the cost approaches zero as the number of people increases. the vertical asymptote x = 8 means the cost approaches zero as the number of people increases.
