Question

Ashley has 100 books that she wants to give away at the rate of n books per week. Write a recursive function that represents the number of books Ashley has at any time. The recursive function that gives the number of books Ashley has at any time is ____=______, started at ____.

Answer 1

f(x) = f(x-1) - n <--- this is the recursive formula

f(0) = 100

f(1) = f(0) - n = 100 - n

f(2) = f(1) - n = 100 - n - n = 100 - 2n

f(3) = f(2) - n = 100 - 2n - n = 100 - 3n

in general the EXPLICIT formula is f(x) = 100 - xn , x=0,1,2,3

hope this helps if it is wrong let me know have a blessed day
