Find f[g(x)].
f(u) = eu; g(x) = -2x7
solution:-
Recall that a function m is a composite of function f and g if the following equation is true.
m(x) = f[g(x)]
The domain of m is the set of all numbers x such that x is in the domain of g and g(x) is in the domain of f.
Find f[g(x)].
f [g(x)]=f[-2x7] Substitute for g(x).
= 
Therefore ,f[g(x)] =
