Answer 1

A. Amount(hours worked)

Explanation:

Function notation is a way of converting a written description of a function to a concise form that is easy to read.

It is another way of representing the y-value in a function, y = ƒ(something)

Let's convert the word expression to function notation:

• "The amount charged for labour depends on the time the repair technician works."

• "The amount depends on the hours worked."

• "The amount is a function of the hours worked."

• Amount = amount(hours worked)

• y = a(h)
