D) The amount earned is a function of the number of years of experience

(B)the amount earned is a function of the number of hours worked.

Step-by-step explanation:

Let the time worked (in hours) worked =t

Let the amount earned =A

From the graph

When t=1, A= $10

When t=2, A= $20

When t=3, A= $30

When t=4, A= $40

When t=5, A= $50

We observe that as t increases, the amount increases.

We can, therefore, conclude that the amount earned is a function of the number of hours worked.
