Question

question 8 (workbook):
lin charges $5.50 per hour to babysit. the amount of money earned, in dollars, is a function of the number of hours that she babysits.
which of the following inputs is impossible for this function?
-1
2
5
8

Explanation:

Step1: Analyze the context

The function represents the number of hours babysat. Since the number of hours cannot be negative (you can't babysit for a negative number of hours), we check each option.

Step2: Evaluate each option

• For -1: Hours can't be negative, so -1 is impossible.
• For 2: 2 hours is a valid positive number of hours.
• For 5: 5 hours is a valid positive number of hours.
• For 8: 8 hours is a valid positive number of hours.

Answer:

-1 (the option with -1)
