Explanation:
Domain is the values of x for which the function is defined. As seen in the graph, we have -∞ < x < ∞, which can be represented by other notations such as x and (-∞, ∞).
Similarly, Range is the values of y for which the function can give as an output. From the graph, we have y ≥ -1, which can be represented by other notations such as y and [-1, ∞).
