Answer:
-4 ≤ x ≤ 8
Explanation:
The domain of a graph refers to the set of all possible input values, which are shown on the x-axis. It represents the range of x-values for which the function is defined1. The domain can be determined by examining the graph and identifying the set of input values that correspond to the x-axis.
In this case, the cubic function shown has been restricted between -4 and 8 along the x-axis. Since this is represented in full dots, we can therefore conclude that -4 and 8 are inclusive of the domain.
This can be represented by -4 ≤ x ≤ 8 or [ -4 , 8 ]
