Answer:
Function: 
Not Function:
and 
Step-by-step explanation:
Given



Required
Determine if
is a function of 
Solving x+y=9

Make y the subject of formula

<em>Hence; y is a function of x</em>
Solving 

Subtract x² from both sides

Square root of both sides

This implies that
or 
<em>Because </em>
<em> can be any of those two expressions, it is not a function.</em>
Solving 

Reorder

Take square roots

This implies that
or 
<em>Because </em>
<em> can be any of those two expressions, it is not a function.</em>
