The domain of f is \((- \infty, \infty)\).
The range of a function is the set of all possible output values (y-values). From the graph, the lowest point on the graph is at y = -4, and the function extends upwards indefinitely.
The range of f is \([-4, \infty)\).
The x-intercepts are the points where the graph crosses the x-axis. From the graph, the function crosses the x-axis at x = -2 and x = 2.
The x-intercepts are \(-2\) and \(2\).
