Final answer:
The zero term for the function f(x) = 13(1.2)^x is 13, as any number to the power of zero is 1.
Step-by-step explanation:
The zero term for the function f(x) = 13(1.2)^x is found by plugging in x = 0 into the function. This yields f(0) = 13(1.2)^0, which simplifies to f(0) = 13 because any number raised to the zero power is 1. Therefore, the zero term for this function is 13.
