Evaluate the expressions. y = f(x), X =f(x)

Question

Evaluate the expressions. y = f(x), X =f(x)

 

a. f(-1) = ?

 

b. f^-1(3) = ?

c. f^-1(0) = ?

d. (f^-1 * f)(3) = ?

Answer 1

 f( X ) = X     f^-1( X ) = X

 

    a) f( -1 ) = -1

 

    b) f ^-1( 3) = 3

 

   c  f ^-1 ( 10) = 10

 

   d)( f^-1 * f ) ( 3) = 3 * 3 =9
