The function f(x) = 5x converts a nickels to pennies. Find a function that converts pennies to nickels. Then convert 50 pennies to nickels.
f-1 (x) = x/10. 50 pennies is equivalent to 5 nickels.
f-1(x) = 5/x. 50 pennies is equivalent to 5 nickels.
f-1(x) = x/5. 50 pennies is equivalent to 10 nickels.
f-1(x) = 5/x. 50 pennies is equivalent to 10 nickels.
