Step 1 ：First, observe that the function is an exponential function with a negative coefficient, which means it will be decreasing and always negative.

Step 2 ：Since the function is always negative, the range of the function will only include negative numbers.

Step 3 ：As x approaches positive infinity, the function will approach 0 from the negative side, but it will never actually reach 0.

Step 4 ：As x approaches negative infinity, the function will decrease without bound, meaning it can take on any large negative value.

Step 5 ：Therefore, the range of the function is all negative real numbers, which can be written in interval notation as \(\boxed{(-\infty, 0)}\).
