Question

Plz, help me!!! Write each interval as an inequality. Then graph the solutions. (–∞,5)

Answer 1

The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.

So we can write $-\infty < x < 5$ which shortens to $x < 5$

The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.
