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.

Answer:</h3>
B). y = (x -3)(x +1)(x -1)
<h3>
Step-by-step explanation:</h3>
The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).
Selection B is the only choice that has these three factors.
_____
<em>Comment on zeros and factors</em>
When x = a is a zero of a polynomial function, (x -a) is a factor.
