<u>ANSWER</u>
It is not one-to-one function
<u>EXPLANATION</u>
A one-to-one function must pass the horizontal line test.
The graph described in the question looks like the one in the attachment.
A horizontal line drawn in red cuts the graph at more than one point.
Therefore the parabola shown facing up with a vertex
is not a one-to-one function.
3/8 is the right answer to that question

Answer:
Each day,
tours are offered.
Step-by-step explanation:
We were given that, the museum starts at,
10:00 AM and closes at 4:00 PM.
The total duration is ![4:00PM-10:00AM=16:00GMT-10:00GMT=6hours](https://tex.z-dn.net/?f=4%3A00PM-10%3A00AM%3D16%3A00GMT-10%3A00GMT%3D6hours)
Since the tour of the museum are offered every
hour each day, we can calculate the number of tours that will be offered within the 6 hours as follows
We rewrite to obtain,
![Number\:of\:tours=6\div \frac{1}{3}](https://tex.z-dn.net/?f=Number%5C%3Aof%5C%3Atours%3D6%5Cdiv%20%5Cfrac%7B1%7D%7B3%7D)
We multiply by the reciprocal of the second fraction to get,
![Number\:of\:tours=6\div \frac{3}{1}=18](https://tex.z-dn.net/?f=Number%5C%3Aof%5C%3Atours%3D6%5Cdiv%20%5Cfrac%7B3%7D%7B1%7D%3D18)
Therefore 18 tours will be offered each day in the art museum.
