Transcript text: Part 2 of 3
(b) $y(x)=\frac{x}{|x+1|+4}$
The domain in interval notation is $\square$ .
Solution
Solution Steps
To determine the domain of the function \( y(x) = \frac{x}{|x+1|+4} \), we need to identify the values of \( x \) for which the function is defined. The function is defined for all real numbers \( x \) because the denominator \( |x+1| + 4 \) is always positive and never zero.
Step 1: Define the Function
The given function is \( y(x) = \frac{x}{|x+1| + 4} \).
Step 2: Analyze the Denominator
The denominator of the function is \( |x+1| + 4 \). Since the absolute value function \( |x+1| \) is always non-negative, and adding 4 ensures that the denominator is always positive and never zero.
Step 3: Determine the Domain
Since the denominator \( |x+1| + 4 \) is always positive for all real numbers \( x \), the function \( y(x) \) is defined for all real numbers.
