Question

Solve the compound inequality. Graph the solution set and write it in interval notation.
x>4 or x<5

Answer 1

Graph:

Answer 2

Because it's a disjunction the solution set is the union of the solution set of the first and the solution set of the second part.

In this question the union of the solution set is all reall numbers so the new graph will be:

Answer 3

So the line will be crossing the whole graph since they meet?
