Solution
To solve the expression , we'll first extract the given functions and , and then evaluate them at and , respectively.
Step 1: Identify the functions
Based on the information provided:
- is given by the following set of values: \begin{cases} 33 & \text{if } x = -8 \\ -3 & \text{if } x = 2 \\ -4 & \text{if } x = -4 \\ 7 & \text{if } x = -3 \\ 6 & \text{if } x = 7 \end{cases}$$
Step 2: Find
From the table of values for , we see that:
