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

Answer:
Answer: about 14
Work Shown:
Add up the values in the table:
170+135+150+145 = 600
There are 600 orders in total. Of those 600, we have 135+145 = 280 that are for lemonade or for orange juice. This means roughly 280/600 = 0.4667 of all the drinks are either lemonade or orange juice.
Assuming this ratio keeps up, we can multiply 0.4667 with 30 to get
30*0.4667 = 14.001 which rounds to 14
This represents the estimated number of drinks in the next 30 orders that are either lemonade or orange juice.
