Answer:
all real numbers less than 0
Step-by-step explanation:
In the picture attached, the question is shown.
The function described is an exponential decay with the form:
y = ab^x
where a = 2 and b = 1/4
The range of an exponential decay function is all real numbers greater than 0. This means that after f(x) has been reflected over the x-axis its range is all real numbers less than 0.
