Answer:

See below

Explanation:

The interval can be written as an inequality as follows: #3 <= x <= 4#
It's #<=# instead of #<# because the square brackets in your question denote that the values listed are included in the interval.

Using a number line, there would be a line over the segment from 3 to 4 and there would be filled in circles on the points 3 and 4.
