The domain: The domain is the set of all x-values for which the function is defined. From the graph, the domain is all real numbers from -2 to 6, inclusive. So, the domain is [-2, 6].
Any x-values for which f(x) = 3: To find x-values where f(x) = 3, locate y = 3 on the graph and find corresponding x-values. The x-value is 0, so x = 0.
The range: The range is the set of all y-values that the function can take. From the graph, the range is all real numbers from -2 to 3, inclusive. So, the range is [-2, 3].
