Question

The following function defines a recursive sequence.
f(0) = -2

f(1) = 8

f(n) = -4•f(n -1) - 3•f(n - 2); for n > 1

Which of the following sequences is defined by this recursive function? (4 points)

Question 4 options:
1) -2, 8, -26, -80, …
2) -2, 8, -26, 80, …
3) -2, 12, -44, 180, …
4) -2, -12, -44, -180, …

Answer 1

Its either option A or B

Answer 2

f(2)=-4 f(1)-3 f(0) = -32+6 = -26
f(3)=-4 f(2) - 3f(1) = 104 - 24 = 80

Answer 3

so its B
