Transcript text: Determine the implied domain of the following function. Express your answer in interval notation.
\[
f(x)=\frac{12}{x-12}
\]
Solution
Solution Steps
To determine the implied domain of the function \( f(x) = \frac{12}{x-12} \), we need to identify the values of \( x \) for which the function is defined. The function is undefined when the denominator is zero. Therefore, we need to find the value of \( x \) that makes the denominator zero and exclude it from the domain.
Step 1: Identify the Denominator
To determine the implied domain of the function \( f(x) = \frac{12}{x-12} \), we first identify the denominator of the function, which is \( x - 12 \).
Step 2: Find the Value that Makes the Denominator Zero
The function is undefined when the denominator is zero. Therefore, we solve the equation:
\[
x - 12 = 0
\]
Solving for \( x \), we get:
\[
x = 12
\]
Step 3: Define the Domain
The domain of the function \( f(x) \) includes all real numbers except \( x = 12 \). In interval notation, this is expressed as:
\[
(-\infty, 12) \cup (12, \infty)
\]
