Problem 1
Use the given information to determine the range of the function f(x):
f(x)
= COS
sin x
Compositions Involving Inverse Functions
Let f : A → B be a bijective function from domain A to codomain B. Then it has an inverse function
f' that maps B back to A. Then
flof = IA or f'(f (x)) = x,
where IA is the identity function in the domain A and x is any element of A.
Similarly,
fo fl= Ig or f (ƒ¯' (3)) = y,
-1
where IB is the identity function in the codomain B and y is any element of B.
