You have x>4 and x>=11 so the common numbers that are included by both of these inequalities is x>=11 aka [11, infinity]. Can't have negative infinity if x is greater than positive numbers.

okay ty so basically if the inequality sign points to the right it’s positive infinity and if it points to the left it’s negative infinity
