Step-by-step explanation: We are given to find the domain of the function that is graphed in the figure.
We can see from the graph that the values of x will give the domain and the corresponding values of y will give the range of the function.
Since the values of x does not go beyond -3 on the negative X-axis and it goes to infinity on the positive X- axis, so the domain will be greater than or equal to -3.
