Answer:
All the graph in attachment ate possible solutions.
Step-by-step explanation:
The graph that has zeros at -3 and 4, will intersect the x-axis at x=-3 and x=4.
The function could be a parabola that opens up or down and intersects the x-axis at x=-3 and x=4.
It could also be a fourth degree polynomial.

Given that after a discount of 40% a furniture was bought for $438. The original price of the furniture will be calculated as follows:
discount=40%
new percentage price=100-40=60%
Original percentage price=100%
New buying price=$438
therefore, the original price was:
100/60×438
=$730
The original price was $730
We can represent each company's graph by the following equations
V = (0.04)*H...............(Company P)
V = (0.06)*H...............(Company S)
(V represents the vacation hours and H the hours worked)
If both work 2080 hours
V1 = (0.04)*(2080) = 83.2 vacation hours..............(Company P)
V2 = (0.06)*(2080) = 124.8 vacation hours ..............(Company S)
124.8 - 83.2 = 41.6 hours
The friend at company S will have about 42 more vacation hours that the friend at company P
