Math Problem Statement
Solution
Let's go through the problem step by step:
Part (a):
You need to find , which means adding the values of the functions and at .
-
From the graph of , you can see that corresponds to the point on the graph where . By looking at the graph, we can estimate that .
-
From the table, is given directly as .
Now, calculate:
Part (b):
This expression requires you to divide by .
- From the table, .
- The function is provided. To find , substitute into :
Now, calculate:
Final answers:
