To find the value of \( f(Q) \), let's proceed step-by-step by analyzing the given table.
First, we examine the row labeled \( x \) to locate the position of \( Q \). The elements in the \( x \) row are:
[tex]\[ 1, 2, 3, 4, K, Q \][/tex]
We see that \( Q \) is the 6th element in this row.
Now, we need to find the corresponding value in the row labeled \( f(x) \). The elements in the \( f(x) \) row are:
[tex]\[ 12, 3, 1, 2, 4, 7 \][/tex]
Since \( Q \) is the 6th element in the \( x \) row, we look at the 6th element in the \( f(x) \) row. The 6th element here is:
[tex]\[ 7 \][/tex]
Therefore, [tex]\( f(Q) = 7 \)[/tex].
