Write the given interval as an inequality involving x, and illustrate the interval using the real number line.

The given interval as inequality involving x:
4 ≤ x ≤ 6
The number line representation:
Explanations:The given interval is [4, 6]
To write the above given interval as an inequality involving x, it means x is in between 4 and 6, with 4 and 6 inclusive.
The mathematical expression as an inequality is shown below:
4 ≤ x ≤ 6
The number line representation of the given interval is shown below:
