Students were requested to answer a question at academics and to claim what is most important for them to succeed. Of the many reactions, one that that stood out was practice. Successful people are generally not born successful; they become successful from hard work and perseverance. If you wish to achieve your goals, keep this in mind! following are one of the answer and question example that you may make use of to practice and improve your practical knowledge and also give you insights that can guide you to keep up your study in school.

## Question:

Everbank Field, home of the Jacksonville Jaguars, is capable of seating 76,867 fans. The revenue for a particular game can be modeled as a function of the number of people in attendance, x. If each ticket costs $161, find the domain and range of this function.

## Answer:

The domain will be every integer from 0 to 76867 (it will look like this [0, 76867].

The range will be {0, 161, 322, 3(161), 4(161), … 76867(161)}.

With the information given, the equation will look like this:

f(x) = 161x

The domain is a set of all possible values that, when plugged into x, will give us a real number. So, if we were to plug in 2 for x, the equation would look like this:

f(2) = 161(2) = 322

Since 322 is a real number, 2 is part of the domain.

While the domain is the set of numbers that substitute x, the range is the product. So in the above example, the range would be 322. Since the domain is [0, 76867], the range would be the set of products that come from plugging in each of these numbers:

{0, 161, 322, 3(161), 4(161), … 76867(161)}

From the answer and question examples above, hopefully, they could simply help the student answer the question they had been looking for and observe of every single thing stated in the answer above. Then could definitely carry out some sharing in a group discussion and also learning with the classmate relating to the topic, so another student also have some enlightenment and still keeps up the school learning.
