If f(x)=x^2 –4, ... x > or equal to 0
and g(x)=sqrt(x+4) ... x > or equal to –4 ,
(a) f(g(x))=
(b) g(f(x))=
(c) Thus g(x) is called an INVERSE function of f(x)
-----
If f is one-to-one and f(–4)=14, then
f^–1 (14)=
and (f(–4))^–1= .
If g is one-to-one and g(4)=4, then
g^–1 (4)=
and (g(4))^–1= .
If h is one-to-one and h(1)=14, then
h^–1 (14)=
and (h(1)^)–1=
