PLEASE HELP Function Stories You’ve seen how we can use different functions to model real-world situations, and you’ve studied t
hose functions to understand how their graphs communicate information about the scenario. To build your understanding of how modeling with mathematics works, you’ll now create ideas for real-world situations in which an existing function could serve as the model. For each question, you will be asked to describe a relationship that could be modeled by the given function. For each question, there is no single correct answer: any scenario that fits the function type is correct. Question 1 Part A Identify the function type in the graph, and then describe a relationship that could be modeled by the function represented by the graph. Part B Identify and interpret the key features of the function in the context of the situation you described in part A.

Since we are trying to find the number of sequences can be made <em>without repetition</em>, we are going to use a combination.
The formula for combinations is:
is the total number of elements in the set
is the number of those elements you are desiring
Since there are 10 total digits, in this scenario. Since we are choosing 6 digits of the 10 for our sequence,
in this scenario. Thus, we are trying to find
. This can be found as shown:
There are 210 total combinations.
