Algebra 2 homework practice workbook
Question:
What are the four primary types of Algebra?
Answer:
Step 1
The range of input values for which f(x) works correctly is called its domain. The output values for f are the range of the function (x). From the problem, we can see that the function has a range of 21–25–30 and a domain of 2.
Step 2
A Sets A and B have a function relationship if every element in set A has at least one value in set B. In the domain of the given function, the value 2 is the same as both 21 and 25. So, the questionable relationship can’t be a function.
Result
Domain= {2,8} Range ={21,25,30}
Not a function
