It does represent the function because each out put has only one input
Answer:

Step-by-step explanation:
This is the product of a binomial (two terms) in the variable y with a trinomial (three terms) in the variable y as well. Arrange the terms of each expression as noted in the attached image, and complete the boxes with the products of each vertical header with each horizontal header in the appropriate cell of the table. Then combine all like terms (marked in orange and green) to get the final answer:

Answer:
<h2>x-intercept = 125 → (125, 0)</h2><h2>y-intercept = 275 → (0, 275)</h2>
Step-by-step explanation:
The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis.
Look at the picture.
Step-by-step explanation:

x varies inversely as y. This means that x is equal to the inverse of y which can be translated as x = 1/y but the problem said that x is <u>n</u><u>o</u><u>t</u><u> </u><u>e</u><u>x</u><u>a</u><u>c</u><u>t</u><u>l</u><u>y</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>l</u><u> </u>to the inverse of y. Therefore, we need to introduce a factor k. Factor k will represent the word "varies" in the problem.
To illustrate:

Since we don't have the value of k, we have to solve for it by using the first values of x and y which was given as x=2 and y=20.

Now that we have the value of k, we can now solve for the value of x when y=5.

Therefore, when y is 5, the value of x is 8.
