Math help please w/ these four questions? It has to deal w/ Function Notation:

*For what value of x does C(x) = 1900?

*Interpret the statement C(20) = 1270.

*Interpret the statement C(w) = p.

*Explain whether C(40.5) = 1341.75 is correct and possible given the context of this problem.

phi · Answer

without details on C(x)  the best you can say for
C(x) = 1900 
is
$$ x = C^{-1}(1900) $$
which says the inverse function of C evaluated at 1900 gives the x value such that C(x)=1900
