The image you've uploaded shows a set of function-related questions involving the graphs of two functions $f(x)$ (in blue) and $g(x)$ (in pink). The tasks involve evaluating the function for specific values of $x$, as well as performing operations such as function addition, composition, and evaluation at given points.

Here’s a breakdown of the tasks:

1. Evaluate $(f+g)(4)$
2. Evaluate $(g-f)(1)$
3. Evaluate $(g-f)(-1)$
4. Evaluate $\left( \frac{1}{g} \right)(-1)$
5. Evaluate $(f \circ g)(2)$
6. Evaluate $(g \circ f)(1)$
7. Evaluate $g(f(4))$

To proceed, I'll analyze the graph to gather the needed values of the functions $f(x)$ and $g(x)$ at the specific $x$-values provided in each part.

Let me first extract the values of $f(x)$ and $g(x)$ at the required points. I'll then help you with each calculation.

Do you want me to go through each part step-by-step and show how the operations are performed?
