[tex](f\circ g)(-3)=4[/tex]
To solve this, we can use the definition of composite functions:
[tex](f\circ g)(x)=f(g(x))[/tex]
Now we just need to find the value of g(-3) and then evaluate that result in f(x)
Looking at the graph, g(-3) = 1
Now we need to find f(1). In the graph we can see that f(1) = 4
Then f(g(-3)) = 4
