Piecewise Word

A shipping company charges $5 for the first pound of a package and $2 for each additional pound. Write a piecewise function to represent the cost of shipping a package that weighs x pounds.

• f(x) = 5 + 2(x-1) if x > 1, f(x) = 5 if x = 1

• f(x) = 2(x-1)

• f(x) = 5x

• f(x) = 5 + 2x

A phone plan charges $30 for the first 500 minutes of talk time and $0.10 per minute for each additional minute. Write a piecewise function to represent the cost of x minutes of talk time.

• f(x) = $30 if x <= 500 f(x) = $30 + ($0.10 * (x - 500)) if x > 500

• f(x) = $30 if x <= 500 f(x) = $0.10 * (x - 500) if x > 500

• f(x) = $30 if x <= 500 f(x) = $0.10 * x if x > 500

• f(x) = $0.10 * x if x <= 500 f(x) = $30 if x > 500

A taxi charges $3.50 for the first mile and $2.50 for each additional mile. Write a piecewise function to represent the cost of a taxi ride that is x miles long.

• f(x) = $3.50 + ($2.50 * (x + 1))

• f(x) = $3.50 + ($2.50 * (x - 1))

• f(x) = $3.50 + ($2.50 * x)

• f(x) = $3.50 + ($2.50 * (x - 2))

A gym membership costs $50 per month for the first 6 months and $30 per month for each additional month. Write a piecewise function to represent the cost of a gym membership for x months.

• f(x) = $50 + ($30 * x) if x <= 6 f(x) = $30 if x > 6.

• f(x) = $50 if x <= 6 f(x) = $30 + ($30 * (x - 6)) if x > 6.

• f(x) = $50 if x <= 6 f(x) = $50 + ($30 * (x - 6)) if x > 6

• f(x) = $50 if x <= 6 f(x) = $30 if x > 6.

A tutoring service charges $40 per hour for the first 2 hours and $30 per hour for each additional hour. Write a piecewise function to represent the cost of x hours of tutoring.

• f(x) = $40x, if x <= 2 f(x) = $30(x-2), if x > 2

• f(x) = $40x, if x <= 2 f(x) = $30(x+2), if x > 2

• f(x) = $40x, if x <= 2 f(x) = $40 + $30(x-2), if x > 2

• f(x) = $40x, if x <= 2 f(x) = $30x, if x > 2

A water park charges $25 for the first 2 hours of admission and $15 for each additional hour. Write a piecewise function to represent the cost of x hours of admission.

• f(x) = $15, if x <= 2

• f(x) = $25, if x <= 2 f(x) = $25 + $15(x-2), if x > 2

• f(x) = $25 + $10(x-2), if x > 2

• f(x) = $25, if x <= 1

A pizza place charges $10 for a small pizza, $15 for a medium pizza, and $20 for a large pizza. Write a piecewise function to represent the cost of ordering x pizzas.

• The piecewise function to represent the cost of ordering x pizzas is: f(x) = 10x for 0 <= x < 5 f(x) = 15x for 5 <= x < 10 f(x) = 20x for x >= 10

• f(x) = 12x for 5 <= x < 10

• f(x) = 5x for 0 <= x < 5

• f(x) = 25x for x >= 10

A movie theater charges $8 for a matinee show and $12 for an evening show. Write a piecewise function to represent the cost of attending x movies.

• f(x) = $8 * x for x > 1

• f(x) = $12 for 0 < x <= 1

• The piecewise function to represent the cost of attending x movies is: f(x) = $0 for x <= 0 f(x) = $8 for 0 < x <= 1 f(x) = $8 + ($12 * (x - 1)) for x > 1

• f(x) = $8 for x <= 0
