Answer:
Therefore the domain of the function is : all real numbers
The range of the function is f(x) ≥ -1
Explanation:
i) The domain of the function in the graph is all real numbers as the graph is plotted from - ∞ to + ∞ on the x axis.
ii) the minimum value of f(x) as can be seen from the plot of the graph is -1 and the maximum value is +∞.
Therefore the domain of the function is : all real numbers
The range of the function is f(x) ≥ -1
