8. Find the values of first four terms of the sequence f(n) when n=2k, where f(n) satisfies the recurrence relation f(n)=f(n/2)+3 with f(1)=2. a) f(2)= b) f(4)= c) f(8)= d) f(16)= 9. Use the forward or backward substitution to find the solution of f(n) when n=2k, where f(n) satisfies the recurrence relation f(n)=f(n/2)+3 with f(1)=2. Your answer: f(n)=
