The set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.
<h3>When does a relation represents a function?</h3>
A set, or a relation, represents a function when <u>each value of x is mapped to only one value of y</u>.
In this problem, we have that option A represents a function, as:
- In option B, x = 2 and x = -2 are mapped to two values.
- In option C, x = 4 is mapped to four values.
- In option D, both x = 1 and x = 2 are mapped to two values.
Hence the set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.

An inverse statement is negating both statements meaning if not p, then not q.
So transforming this to an inverse statement would be:
<span>If two out of five people don’t use the subway every day, then the probability of a person using the subway isn’t 0.4. So the answer B.</span>
        
             
        
        
        
The equation you would use to find her earning for the week would be:
y=0.03(x-1000)+150
This would mean she made $66 from commissions and $216 total.

Answer:
$872
Step-by-step explanation:
Simple interest = Principle * Rate * Time / 100
= ( 800 * 6 * 18/12 ) / 100
= $ 72
The balance after 18 months = principle + interest
= 800 + 72
= $ 872
