WebJun 5, 2012 · 3. I think it's a difference equation. You're given two starting values: f (0) = 1 f (1) = 1 f (n) = 3*f (n-1) + 2*f (n-2) So now you can keep going like this: f (2) = 3*f (1) + 2*f (0) = 3 + 2 = 5 f (3) = 3*f (2) + 2*f (1) = 15 + 2 = 17. So your recursive method would look like this (I'll write Java-like notation): WebJan 8, 2024 · This is a geometric series with a=f(1)=1 and r=-3. f(n)=f(1)(-3) n-1 You plug in n=5 to get the answer.

WebFeb 14, 2014 · I agree that n⋅2ⁿ is not in O(2ⁿ), but I thought it should be more explicit since the limit superior usage doesn't always hold.. By the formal definition of Big-O: f(n) is in O(g(n)) if there exist constants c > 0 and n₀ ≥ 0 such that for all n ≥ n₀ we have f(n) ≤ c⋅g(n).It can easily be shown that no such constants exist for f(n) = n⋅2ⁿ and g(n) = 2ⁿ.
WebOct 29, 2024 · The value of f(5) = 4375 in f(n) = 5f (n − 1). What is multiplication? Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times. Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
