Questions: Select the domain and range of the graph in set-builder and interval notation.
Domain = x x ∈ R or (-∞, ∞)
Range = y y ∈ R or (-∞, ∞)
Transcript text: Select the domain and range of the graph in set-builder and interval notation.
Domain $=$ $\{x \mid x \in \mathbb{R}\}$ or $(-\infty, \infty)$
Range $=$ $\{ y \mid y \in \mathbb{R}\}$ or $(-\infty, \infty)$
Solution
Solution Steps
Step 1: Identify the Domain
The domain of a function is the set of all possible input values (x-values) that the function can accept. Observing the graph, the curve extends infinitely in both the positive and negative x-directions. Therefore, the domain includes all real numbers.
Step 2: Identify the Range
The range of a function is the set of all possible output values (y-values) that the function can produce. Observing the graph, the curve extends infinitely in both the positive and negative y-directions. Therefore, the range includes all real numbers.
Step 3: Express the Domain and Range in Set-Builder and Interval Notation
Domain in Set-Builder Notation: \(\{x \mid x \in \mathbb{R}\}\)
Domain in Interval Notation: \((-\infty, \infty)\)
Range in Set-Builder Notation: \(\{y \mid y \in \mathbb{R}\}\)
Range in Interval Notation: \((-\infty, \infty)\)
Final Answer
Domain: \(\{x \mid x \in \mathbb{R}\}\) or \((-\infty, \infty)\)
Range: \(\{y \mid y \in \mathbb{R}\}\) or \((-\infty, \infty)\)
