Work in teams of three or four (person A, person B, and person C). Each student is to complete his or her worksheet using the me
thod as prescribed on the sheet, showing all work for each problem. When you are finished, compare solutions for each corresponding system. Write the agreed upon
solution in the appropriate column. Then discuss how Vou arrived at your solution. Was the method
you used easier or more difficult than the others? Decide which method or methods the group found
to be the 'best' or 'preferred' for each system (graphing, substitution or elimination). Give a reaso
for your answer. Simply saying, "it was the easiest method" is not sufficient. Explain WHY you found
the method to be the best-what made it easier?

Answer:
1. All real numbers
2. All real numbers except y = 0
3. All real numbers except x = -7
4. All real numbers except b = 10
Step-by-step explanation:
For any function to be defined at a particular value, it should not be <em>approaching to a value </em><em> or it should not give us the </em>
<em> (zero by zero) form </em> when the input is given to the function.
The value of function will depend on the denominator.
Now, let us consider the given functions one by one:
1. 5y+2
Here denominator is 1. So, it can not attain a value or
<em> (zero by zero) form </em>
So, for all real numbers, the function is defined.
At y = 0, the value
So, the given function is <em>defined for all real numbers except y = 0</em>
<em></em>
<em></em><em></em>
Let us consider denominator:
x + 7 can be zero at a value x = -7
So, the given function is <em>defined for all real numbers except x = -7</em>
<em></em>
Let us consider denominator:
10-b can be zero at a value b = 10
So, the given function is <em>defined for all real numbers except b = 10</em>
