The graph shows the relationship between the amount of change given from a $10 bill and the number of bagels purchased.
A graph shows number of bagels labeled 1 to 10 on the horizontal axis and change given (dollar sign) on the vertical axis. A line decreases from 0 to 10.
What function represents the amount of change given from a $10 bill, f(x), based on x, the number of bagels purchased?
f(x) = + 10
f(x) = + 10
f(x) = + 10
f(x) = + 10
1 answer
f(x) = 10 - x
