Answer:
A union (UNION(x,y)) of the sets Sx and Sy represented by x and y, respectively will perform ________4_________ update(s) of the attribute.
Explanation:
The UNION (x, y) disjoint-set data structure unites the dynamic sets that contain x and y, say Sx and Sy, into a new set. It is called the union of the two sets. Before the union operation, the two sets are disjoint. After the union operation, the representative of the resulting set is some member of Sx and Sy or either Sx or Sy. The sets Sx and Sy are then destroyed to remove them from the union collection S. So, four operations are required.

Explanation:
Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents. There are different types of functions used in Microsoft Excel to perform specific tasks and these includes;
1. VLOOKUP function: it's an Excel function that avails end users the ability to lookup data in a table organized vertically. Thus, it's typically used for searching values in a column.
2. SUMIF function: it is an Excel function to sum cells that meet criteria such as text, dates and numbers. This function can be used with the following logical operators; <, >, and =.
3. COUNT function: it's an Excel function to find the total number of entries in a column. For example, to count the number of entries in B1:B15; COUNT(B2:B15).
4. IF function: runs a logical test and returns one value for a TRUE result, and another for a FALSE result. For example, to fail scores that are below 40; IF (A1 < 40, "Fail", "Pass").
5. HLOOKUP function: it's an Excel function that avails end users the ability to lookup data in a table organized horizontally. Thus, it's typically used for searching values in a column.
