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

Answer:
So we will be saving a total of $0.7 at new rate
Step-by-step explanation:
Given:
Original price =$ 0.69
New price = $ 2.75 per 5 switches
To find:
Saving = ?
Solution:
The original per price of the switch is given as = $ 0.69
Discounted price of 5 switches at $2.75
5 Switch price at original price = Original price * No of switches
= 0.69 * 5
= $ 3.45
Total saving at buying 5 switches = 3.45 - 2.75
=$0.7
So we will be saving a total of $0.7 at new rate
Add the sales tax from the discounted price
