Answer:
A
Step-by-step explanation:
The answer is x^2+11x+(121/4)=(143/4)
We know that charges vary with the days of the week. E.g. Go-karting costs higher ($10) on Saturday and Sunday compared to on Monday to Friday ($5)
We need to know if the cost is a function of the activity type ?
We know that the cost varies with the day. So the cost is a function of the day of the week. On weekdays the function yields a lower value, whereas on weekends it yields a higher value.
Since the cost for a particular activity is changing and not staying constant, <u>hence the cost is not a function of activity type.</u>
