Answer:

The answer to your question is:

Domain [0, 8)

Range [-3, 1]

f(0) = -3

Step-by-step 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
