Answer:
Step-by-step explanation:
All relations that have an inverse are functions.
- <em>The value of </em>
<em> is 3</em> - <em>The value of </em>
<em> is 6</em>
<em />
The function is given as:

<u>(a) The value of </u>
<u />
From the table (see attachment), we have:

Take inverse of both sides

Rewrite as:

Hence, the value of
is 3
<u>(b) The value of </u>
<u />
From the table (see attachment), we have:

Take inverse of both sides

Rewrite as:

Hence, the value of
is 6
