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.
