The function is applicable within the segments of x:
(-∞, -1) and [-1, 7), meaning it is valid for x < 7.
Importantly,
the function cannot be evaluated at x = -1 in the left part of the linear graph, while it is valid at x = -1 in the right segment of the same line. Additionally, the function is not defined at x = 7 or any value above it.
Conclusion: x < 7.
He rents the car for d days, but receives two days at no cost, meaning he only needs to pay for d - 2 days.
Each day's rental costs $45, so for d - 2 days, the cost is 45(d - 2). The total expenditure amounts to $315, leading to the equation
45(d - 2) = 315
Now, let's solve for d, the number of days rented.
45(d - 2) = 315
45d - 90 = 315
45d = 405
d = 9
He rented the car for 9 days.

Answer:
The cost of an ice cream cone with 5 scoops is $4.5
Step-by-step explanation:
According to the prompt:
An ice cream stand formulates the pricing for an ice cream cone containing x scoops as follows 
C(x) = .....[1]
Given that: x = 5 scoops
We seek to determine the cost for an ice cream cone containing 5 scoops.
Inserting x = 5 into [1] yields;
C(5) = 
C(5) = 
= 2 + 2.5 = $4.5
Consequently, the price for an ice cream cone with 5 scoops is $4.5
