You have to find:
[tex](f+g)(-2)[/tex]
Notice that the Linear Function f(x) and the Linear Function g(x) must be added, in order to find:
[tex](f+g)(x)[/tex]
Then, analyzing the graph, you can identify that:
Notice that, when:
[tex]\begin{gathered} f(-2)=3 \\ g(-2)=1 \end{gathered}[/tex]
Therefore:
Hence, the answer is:
[tex](f+g)(-2)=4[/tex]
