Based on the graph shown above, an inequality that best represents the domain of the part shown is: C. All real numbers greater than or equal to -6 and less than 8.
In Mathematics and Geometry, a domain is the set of all real numbers (x-values) for which a particular function (equation) is defined.
Generally speaking, the horizontal section of any graph is typically used for the representation of all domain values. Additionally, domain values are both read and written by starting from smaller numerical values to larger numerical values, which implies from the left of a graph to the right of the coordinate axis.
By critically observing the graph shown in the image attached below, we can reasonably and logically deduce the following domain and range:
Domain = [-6, 8] or -6 ≤ x < 8.
Range = (-3, 5] or -3 < x ≤ 5.
