# 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
