Answer 1

@quickstudent @.Sam. help me

Answer 2

When f(1), use the top function, f(x)=-16,
When f(1)=-16
-----------------------------
When 'n' is more than 1, which means n>1, you use the bottom function because 2 is greater than 1. So
f(n)=f(n-1)*(-1/2), n=2,
f(2)=f(1)*(-1/2)=-16*(-1/2)=8

Answer 3

Same goes for f(3) and f(4), since both of them are greater than 1, you use the bottom function
