Answer:
f(4) = -256
Explanation:
A recursive formula defines the nth term of a sequence based on the values of earlier terms.
To find the value of f(4) using the given recursive formula, we can work our way up from f(1) using the formula repeatedly.
Given recursive rule:

To find f(2):

To find f(3):

To find f(4):

Therefore, the value of f(4) is -256.
