Final answer:
The value of f(3) based on the given recursive formula is -12.
Step-by-step explanation:
To find the value of f(3) based on the given recursive formula, we start by using the given initial condition f(0)=-12. Then, we can use the equation f(x)=f(x-1)=4 to find the value of f(3).
Using the equation, we have:
f(3) = f(2) = 4
f(2) = f(1) = 4
f(1) = f(0) = -12
Therefore, the value of f(3) is -12.
