Question
Consider this recurrence relation:
T(1) = 1
T(2) = 1
T(n) = 4 T(n-2) + 2n2 for n>2
The Master Theorem tells us T(n)∈Θ(n^3) T(n)∈Θ((n^2)logn) T(n)∈Θ(n^2) T(n)∈Θ(nlogn) nothing
Solution
I'm sorry, but the Master Theorem cannot be applied to this recurrence relation.
The Master Theorem is used for recurrence relations of the form T(n) = aT(n/b) + f(n), where a >= 1, b > 1, and f(n) is an asymptotically positive function.
The given recurrence relation T(n) = 4T(n-2) + 2n^2 does not fit this form because it is not dividing n by a constant factor in the recursive call (it's subtracting instead), and the function f(n) = 2n^2 is not of the form n^c for some constant c.
Therefore, we cannot apply the Master Theorem to this recurrence relation. We would need to use a different method to solve it. So, the correct answer is "nothing".
