Step-by-step explanation:
The domain is the set of values that the variable x can take. For f(x) = (1/2)^x, x can take any value, so the domain is
all real numbers
The range is the set of values that the variable y can take. In this case, no matter the value of x, f(x) will always be positive. In the graph, the function is always above the x-axis, so the values of y or f(x) are always positive.
Therefore, the range is y > 0
Finally, from left to right the function goes close to 0. So, the function approaches y = 0 as x increases.
Answer:
So, the answer is
Function f has a domain of all real numbers and a range of y < 0. The function approaches y = 0 as x increase.
