Answer:
Yes, the relation is a function
Domain = {-3,1,3,7}
Range = {7,3,1-1}
Explanation:
Given
{(-3,7),(1,3),(3,1),(7,-1)}
To determine if the relation is a function or not, we check if every output has only one corresponding input.
The output are (7,3,1-1) while the input are (-3,1,3,7)
-3 ----;> 7
1 -------> 3
3 -------> 1
7 -------> -1
It is a function since every output only has one corresponding input
To find the domain, we look at the set of input values
Domain = {-3,1,3,7}
To find the range, we look at the set of output values
Range = {7,3,1-1}

Explanation:
In FlashCard.java, we create a FlashCard class with two instance variable, Question and Answer (Line 2 - 3). There is a constructor that takes two input strings to initialize the Question and Answer instance variables (Line 5-8). There is also a toString method that will return the predefined output string of question answer (Line 10 - 15). And also another equals method that will take an input string and check against with the Answer using string equals method. If matched, return True (Line 17 -24).
In Main.java, create three FlashCard object (Line 3-5) and then put them into an array (Line 6). Use a for loop to print the object (Line 8-10). The sample output is as follows:
Question: What is highest mountain?
Answer: Everest
Question: What is natural satelite of earth?
Answer: Moon
Question: Who is the first president of US?
Answer: George Washington
