Acustomer`s total purchase comes to $7.75. the customer gives you a $10 bill, but you mistakenly key in $100. the register indicates the change is $92.25. how much money do you give back?

The correct change for a $10 bill is 2.25, if you key in $100 instead of $10 just take away the 1st digit, and you will have the correct change.

Thank you for posting your question here. The question seems to be unclear. A function is a relation in which each element of the domain is paired with exactly one element of the range. When x = 0, y = 1 and y = 6. So, this relation is not a function. SOLUTION: This is a function because no vertical line can be drawn so that it intersects the graph more than once.
