Step-by-step explanation:
sure, it's a piecewise function and b/c they are asking for f(4) we can just use the lower formula in the definition, soo
f(4-1) + 5.5
then f(4-1) = f(3) where n= 3 is still greater than 1 soo
f(3-1)+5.5
f(2-1) + 5.5
f(1) = 3.5
f(4) + f(3) + f(2)+ f(1)
5.5 +5.5 +5.5+3.5=20
f(4) = 20 :)
