Graph 1 spans (-∞, 5] and [-6, ∞). Graph 3 covers [-1, ∞), Graph 4 includes (-∞, -4], and Graph 5 represents [-2, ∞). Graph 6 extends from (-∞, 3].
The given notation describes the domains (x-values) of six different mathematical graphs. Graph 1 spans from negative infinity to 5, excluding 5. Graph 3 includes all real numbers greater than or equal to -1. Graph 4 covers all real numbers less than or equal to -4.
Graph 5 consists of all real numbers greater than -2. Graph 6 encompasses all real numbers less than or equal to 3. In each case, the square brackets denote inclusion, while round brackets denote exclusion. These notations define the intervals on the x-axis for which each graph is defined.
For example, Graph 1 is defined for x values from negative infinity to 5 (exclusive). Understanding these interval notations is crucial for interpreting and graphing mathematical functions accurately.
