Chapter 2 - Section 2.2 - Graphs of Functions - Exercise Set - Page 122: 35


Domain: $[-2, 6]$ Range: $[-2, 6]$

Work Step by Step

Some important observations about the graph: (i) The lowest point is at $(6, -2)$. (ii) The highest point is at $(-2, 6)$. (iii) The graph is decreasing from left to right. The domain is the set that contains all the x-values of a function. The x-values included in the given function vary from $-2$ to $6$. Thus, the domain of the given function is $[-2, 6]$. The range of a function is the set of y-values. Notice that the y-values included in the graph of the function vary from $-2$ to $6$. Thus, the range of the function is $[-2, 6]$.
