Find the area of domain (no need to solve)
Find the area of domain (no need to solve)
To solve the problem, follow these steps:
Step 1: Identify where each denominator is zero to find the domain restrictions.
Step 2: Solve each condition separately to exclude the non-permissible values.
Now, let's work through each step:
Step 1: The first expression involves the denominator . Set it to zero:
Solve for :
This means the function is undefined for .
Step 2: The second expression involves the denominator . Set it to zero:
Solve for :
This means the function is undefined for .
The domain of this expression is all real numbers except where these denominators are zero. Therefore, the domain restriction is:
The values of cannot equal 1 or , which corresponds to choice 3.
Therefore, the solution to the problem is .
