Step-by-step explanation:
<em>Incomplete question: Missing Attachment</em>
<em>I will answer your question with the attached histogram</em>

Required
Determine the number of tall buildings that had more than 60 floors
The histogram can be interpreted as follows:
More than 60 floors is represented with the following group: 61 - 80
The frequency of group 61 - 80 is 10
<em>Hence, 10 buildings had more than 60 floors</em>
A piecewise-defined function is one that you define not by a single equation, but by two or more. From the figure, we know that this piecewise-defined function is defined by three equations, so our goal is to find each. Two of these equations are constant functions while the other equation is a linear function. So:
1. FOR THE FIRST CONSTANT FUNCTION:
Keep in mind that for this constant function at x = 2, it isn't defined, that's why we choose the symbol <
2. FOR THE LINEAR FUNCTION:
Keep in mind that for this linear function at x = 3, it isn't defined, that's why we use the symbol <
3. FOR THE SECOND CONSTANT FUNCTION:
Keep in mind that for this constant function at x = 3, it is defined, that's why we choose the symbol ≥
In conclusion, the function is:
