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 .
Select the the domain of the following fraction:
\( \frac{6}{x} \)
Domain restrictions tell you which x-values are forbidden because they make denominators zero. This prevents division by zero errors and helps you understand where the equation is actually valid!
The domain shows which x-values are allowed in the equation, while solving finds which x-values make the equation true. You need both for complete understanding!
Convert to improper fraction first: . Then write the restriction as x ≠ 6/5 or keep it as the mixed number x ≠ 1⅕.
No! Domain restrictions are forbidden values that make denominators zero. If a solution equals a domain restriction, then there's no solution to the equation.
Not always! It depends on how many different denominators you have. Each unique denominator can create one restriction, so you might have 1, 2, 3, or more restrictions.
