Answer:
C. [tex]g\,\circ \, f (x) =g(f(x))[/tex]
Step-by-step explanation:
Let be [tex]f(x) = x-500000[/tex] the excedent on annual sales and [tex]g(x) = 0.2\cdot x[/tex] the bonus factor, to determine the bonus amount a composition of [tex]f(x)[/tex] is [tex]g(x)[/tex] must be done. That is:
[tex]g\,\circ \, f (x) =g(f(x))[/tex]
Hence, the right answer is C.
