Suppose the following formula is used to look up the letter grade corresponding to the course average that appears in cell AJ$9$ in the scores$2$ sheet:

parameters$2!$$B$$4$:$E$$14,2)$

The purpose of the VLOOKUP function is to look up a value in a table and:

Interpolate the corresponding value from other columns in the table

Replace the corresponding value from another column in the table

Insert the looked up value into another column at the end of the table

Return the corresponding value from another column in the table
