(A)
The value of g(1) is:
[tex]g(1)[/tex]
At the value of x=1 then output is 3. that mean g(1)=3
Then f(g(1) is convert in f(3)
the x=3 the graph f(x) show output is 6 .
so:
[tex]f(g(1))=6[/tex]
(B)
Value of f(2) is the graph output at the point x=2 is 5 then
g(f(2)) convert in g(5)
The graph g(x) at x=5 output is 3 then the vaqlue is:
[tex]\begin{gathered} g(f(2))=g(f(2) \\ g(f(2))=g(5) \\ g(f(2))=3 \end{gathered}[/tex]
