Jika f(n) = f(n-1)+2n dan f(0)= -3,nilai f(2) = ....

semoga membantu
jangan lupa follow ya

f(n) = f(n - 1) + 2n
f(0) = -3

f(0) = f(0 - 1) + 2(0)
-3 = f(-1) + 0
f(-1) = -3

f(1) = f(1 - 1) + 2(1)
f(1) = f(0) + 2
f(1) = -3 + 2
f(1) = -1

f(2) = f(2 - 1) + 2(2)
f(2) = f(1) + 4
f(2) = -1 + 4
f(2) = 3
