Express the setW={x∣x>2} using interval notation.

This set is numbers strictly greater than 2.

Because this relation is strict (> instead of >=), the left interval is a parens. There is no upper bound, so the right interval is infinity.

(2, +INF)

To express the set W = {x | x > 2} using interval notation, we need to find the interval that represents all the numbers greater than 2.

In interval notation, we use square brackets [ ] for inclusive boundaries (including the number) and parentheses ( ) for exclusive boundaries (excluding the number).

Since the set W consists of all numbers greater than 2, we can express it as an open interval with 2 as the lower bound:

W = (2, ∞)

Here, the parentheses indicate that 2 is excluded from the set, and the infinity symbol (∞) indicates that the set extends indefinitely to the right.
