The problem asks us to find the domain and range of the given graph in interval notation. Since no endpoints are visible, we assume the graph continues forever in both directions where the lines are visible.

1. Problem Description

The problem asks us to find the domain and range of the given graph in interval notation. Since no endpoints are visible, we assume the graph continues forever in both directions where the lines are visible.

2. Solution Steps

* Domain: The domain is the set of all possible $x$-values for which the function is defined. From the graph, the function extends indefinitely in both the positive and negative $x$ directions. Therefore, the domain is all real numbers.

* Range: The range is the set of all possible $y$-values for which the function is defined. From the graph, the minimum $y$-value is $3$. The $y$-values increase indefinitely. Thus, the range starts at $3$ (inclusive) and goes to infinity.

3. Final Answer

Domain: (-oo,oo)

Range: [3,oo)
