Jerome has $150 in his savings account and saves $40 per month. Write a linear function J(x) that will tell us the money Jerome has in his savings account after x months.

• J(x) = 150 + 40

• J(x) = 40x + 150

• J(x) = 150x + 40

• J(x) = 40 + 150

A plumber charges $50 for a house call plus $12 per hour for labor. The linear function P(x) represents the cost of the plumber for x hours.

• $98

• $110

• $74

The following is not a function because...

• There are two values that equal 2.
