A closed interval is one that includes its endpoints: for example, the set { x -3 ≤ x ≤ 1} . … WebThe range is simply y ≤ 2. The summary of domain and range is the following: Example 4: Find the domain and range of the quadratic function. y = {x^2} + 4x - 1 y = x2 + 4x − 1. Just like our previous examples, a quadratic function will always have a domain of all x values. I want to go over this particular example because the minimum or ...
