Answer:
Part A: yes it is a function because every input value (x) produces only one output value (y).
Note: It is still a function if different x values produce the same y value, in this case, x=1 and x=-1 produce the same y value 1, but it is NOT a function if y=1 and y=-1 have the same x value x=1.
Part B: when x=30: f(30)=17*30+50=560
if means that the cost of renting the truck for 30 hours is 560 dollars.

3 of 5 because you can halve each number for example 6 can be halved to make 3 and 10 can be halved to make 5
It will take 12 truckloads to fill up one warehouse. Hope this helps.
X+5=9
subtract 5 from each side
x=4
The answer should be:
cos (0.8 x)
