An inverse function will simply reverse the coordinate pairs of the original function. If f(x)=(x,y), f^-(x)=(y,x).
So 18 is H
...
If f(x)=y=3x-4, to find the inverse function, solve for x, and then reverse the labels as seen below...
y=3x-4
y+4=3x
(y+4)/3=x so the inverse function is:
y=(x+4)/3

I calculated it logically
Answer:
20x+4.99=y
Step-by-step explanation:
Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.
