You paid $120 for a membership to a racquetball club. Court time is $4 per hour. Write a model that represents your average cost per hour of court time as a function of the number of hours played.


a. f left parenthesis x right parenthesis space equals 4 over x plus 120

b. f left parenthesis x right parenthesis space equals space fraction numerator 120 plus 4 x over denominator 4 end fraction

c. f left parenthesis x right parenthesis space equals fraction numerator 120 plus 4 x over denominator x end fraction

d. f left parenthesis x right parenthesis space equals x over 4 plus space 120



You paid $120 for a membership to a racquetball club. Court time is $4 per hour. Write a model that represents your average cost per hour of court time as a function of the number of hours played. What is the horizontal asymptote of this model and what does the asymptote represent?


a. y​ = 0; This asymptote represents the minimum amount paid per hour of court time.

b. y​ = 4; This asymptote represents the minimum amount paid per hour of court time.

c. y​ = 0; This asymptote represents the total number of hours of court time that needs to be paid for.

d. y​ = 4; This asymptote represents the total number of hours of court time that needs to be paid for.
