Considering the given functions in the graph, we have that:
<h3>How to find (f + g)(3) looking at the graph?</h3>
We look at the graph, and find f(3) and g(3), then add them. Hence:
Then the addition is:
(f + g)(3) = f(3) + g(3) = 0 + 4 = 4.
<h3>As for (f - g)(1):</h3>
Same logic, at the graph we have that:
Hence:
(f - g)(1) = f(1) - g(1) = -1 - 1 = -2.

Answer:
x > -18
Step-by-step explanation:
If x was -18, -18/3 is -6 and -6-6 is -12. So, x must be greater than -18.
R's x coordinate is 4 and 6 units away from S's x coordinate, 2. Therefore, the length of side RS is 6 units.
