Step-by-step Solution
To find the inverse of the relation \( R=\{(x \cdot y)=y=4x+2\} \), we need to switch the roles of \( x \) and \( y \) and then solve for the new \( y \).
Given relation: \( R=\{(x \cdot y)=y=4x+2\} \)
1. Switch \( x \) and \( y \):
\( x = 4y + 2 \)
2. Solve for \( y \):
\( x = 4y + 2 \)
\( 4y = x - 2 \)
\( y = \frac{x - 2}{4} \)
Therefore, the inverse of the relation \( R \) is \( R^{-1}=\{(x \cdot y)=y=\frac{x - 2}{4}\} \).
Quick Answer
The inverse of the relation \( R \) is \( R^{-1}=\{(x \cdot y)=y=\frac{x - 2}{4}\} \).
