Use \( U \) to union two or more intervals. Use \( \infty \) (two lowercase o's) for \(\infty\), and DNE if the set is empty. For those not familiar with interval notation, here's some examples of how inequalities are written in interval notation: | Inequality | Interval Notation | |------------|-------------------| | \( 4 \leq x < 7 \) | \([4,7)\) | | \( x < 2 \) | \((-\infty, 2)\) | | \( x \geq 3 \) | \([3, \infty)\) | | all real numbers | \((-\infty, \infty)\) | | \( x < 2 \text{ or } x > 3 \) | \((-\infty, 2) \cup (3, \infty)\) | **Try it out**: Write the interval of values shown in the line graph below. The graph shows a number line with a closed circle at \(-2\) and an open circle at \(3\), with shading between these points. This represents the interval \([-2, 3)\). **Interval is:** \([-2, 3)\) [Submit Question]
