Draw the graph of `f(x)= [sqrtx], x in [0, 16)`, where `[*]` denotes the greatest ineger function.

Explanation

To draw the graph of the function \( f(x) = \lfloor \sqrt{x} \rfloor \) where \( x \) is in the interval \([0, 16)\), we will follow these steps:

### Step 1: Understand the Function
The function \( f(x) = \lfloor \sqrt{x} \rfloor \) means we take the square root of \( x \) and then apply the greatest integer function (floor function), which gives the largest integer less than or equal to \( \sqrt{x} \).

### Step 2: Determine the Intervals
We will analyze the function in different intervals based on the values of \( \sqrt{x} \):
