Answer:
B
Step-by-step explanation:
Because there are 2 different y values for the x value of 5. All x values can only have 1 y value.
For B, there are y points on the x value of 5, so this fails the vertical line test, and is therefore not a function
9.95(0.75)(1.06)=7.91
The .75 is the coupon and 1.06 is the sales tax.

F(x) = [(9,11),(-11,4),(7,-6),(11,-1), (-6,-15),(-13,-5)].

Using the inverse functions property:
- f⁻¹(f(93)) = m = 93
- f(7) = n = -6
<h3>
How to find the values of m and n?</h3>
Two functions f(x) and f⁻¹(x) are inverses if:
f( f⁻¹(x) ) = x
f⁻¹(f(x)) = x
We want to get:
f⁻¹(f(93)) = m
By using the above definition we get:
f⁻¹(f(93)) = m = 93
Now for the second one we want:
f(7) = n
If you look at the table, you can see that f(x) contains the point (7, -6), then:
f(7) = n = -6
