Solution

Solution Steps

Step 1: Identify the Function's Domain

The domain of a function is the set of all possible input values (x-values) for which the function is defined. Observing the graph, the function appears to extend infinitely in both the positive and negative x-directions. Therefore, the domain includes all real numbers.

Step 2: Identify the Function's Range

The range of a function is the set of all possible output values (y-values) that the function can produce. From the graph, the function reaches a minimum value at y = -5 and extends infinitely upwards. Therefore, the range includes all real numbers greater than or equal to -5.
