Run Markdown . Validate Question 3a: Compound Interest with Regular Deposits (2 points) It p in the bank's Interest rate in decimal (0.9., 0.05 moana 5%.) per year, an initial amount a will grow after years to a(1 + p) Write a Python function growtha, P, n) that returns the future value (that is, the total amount of funds), starting with amount arato p. for n years. You can assume that all parameters are non-negative (Your solution does not need to check for that condition, it should simply assume It) The input D represents the interest rate as a floating point number In [16): def growth(a, P. n): # Your Code Here! swa pow(1+0,6) returns # YOUR CODE HERE In (17): growth (340000,0.0314,25) 736473.447868039 Out (17) True In 181: growth (10,0.01, 10) - 11.046221254112001 Out 1181: True In 1911 growth (65,100,3) - 66968565 Out 1071 True In 11 In 1: In Question 3b (1 point) What is the difference in savings if you invest $2000 for 20 years at 2% vs. 1% interest?
