Answer:
e is a function; f is not a function
Step-by-step explanation:
All functions must pass the vertical line test. this means that the when those points are plotted, no two points are on the same vertical line. You can tell if they are on the same vertical line by their x-coordinate. If two points have the same x-coordinate, then they are on the same vertical line. This means that the if two points have the same x-coordinate in the relationship, it is not a function. In e, the x-coordinates are 0, 4, 8, and 3. In f, the x-coordinates are 0, 4, 0, and 6. In e, all the x-coordinates are different, so it is a function. In f, however, 0 is a repeated x-coordinate, so it is not a function.
It is b is the answer to the question
Answer:
<h2>77.3%</h2>
Step-by-step explanation:
Percentage decrease = new amount / old amount
<u />
2619 / 3388 = 0.7730224321
<u>Multiply by 100 to make it a percentage and then round it to the nearest tenth.</u>
<u />
0.7730224321 * 10 =
77.30224321
<u>Rounded</u>
77.3
