4.3.2 Given a function F(n) = (2n-3t)(3n-t), where t is a negative integer and n is an index. I- Find the value soft if F(0)=12 ii- List the values of F(n)for n=1, 2,and 3 iii- Write a recursive formula of the above function. iv- Verify the validity of your recursive function by comparing it with the ones in (ii).
