Okay, so i see that you need help with this problem, and this one is a step function.
00:06
And it says a chainsaw rental firm charges $17 per day or fraction of a day to rent a saw.
00:15
So $17 per day to rent a saw plus a fixed fee, so plus a fixed fee of $4, fixed fee for sharpening the blade.
00:40
Additional portions of the day are considered to be full days rental.
00:46
So rounding upward to identify an entire rental period may be necessary.
00:54
So let s of x represent the cost of renting the saw for x days, complete parts a through h.
01:04
Okay.
01:04
So if s of x, it would be $4 plus $17 a day.
01:15
So find the total number of days someone, okay, so h, a portion of the graph of y equals s of x is shown here.
01:26
Explain how the graph could be continued.
01:29
So it starts from zero to one days, it's 21 because 4 plus 6.
01:36
17 times 1 equals 21...
