Consider the following graph.
Assuming that $f$ is the red function and $g$
is the black one, match the following expressions with their correct
answer.
Recall that by definition $(f\circ g)(x)=f(g(x))$.
$(f \circ g)(5)=$
$1$
$(g \circ f)(5)=$
$2$
$(f \circ g)(0)=$
$1$
$(f \circ f)(5)=$
$4$
$(g \circ g)(5)=$
$0$
$(g \circ g)(-3)=$
$1$
$(g \circ g)(-1)=$
$-1$
$(f \circ g)(1)=$
$-1$
$(g \circ f)(1)=$
$-1$
$(f \circ f \circ g)(4)=$
$3$
$(g \circ f \circ f)(4)=$
$1$
$(f \circ g \circ f)(4)=$
$2$
