How is the inequality x greater than 3 written in interval notation?

1. Every number to the right of 3 satisfies the inequality, but 3 itself does not. 2. An excluded endpoint is written with a parenthesis rather than a bracket. 3. There is no upper end, so infinity closes the interval, giving (3, infinity). _Source: OpenStax Intermediate Algebra (CC BY 4.0), Ch 2 "Solving Linear Equations", section 2.5 Solve Linear Inequalities_
