Answer:
The answer to your question is:
Domain [0, 8)
Range [-3, 1]
f(0) = -3
Explanation:
Domain: is the possible values that the "x" can take
Range: are the values that take the function when is evaluated by the independent variable (x).
For this example:
Domain [0, 8) close is zero and open in 8
Range [-3, 1] close in both sides
f(0) = -3
