Question

If A = (1,2,3,4,)
B = (2,4,6,8.)
f(1) = 2, f(2) = 4, f(3) = 6 and f(4) = 8, And f:A - B then f inverse
is :​

Answer 1

Answer:

A=(1,2,3,4,)

B=(2,4,6,8)

A-B=(1,2,3,4)-(2,4,6,8,)

Answer 2

Answer:

Here you go .............

Step-by-step explanation:

Since f is a bijective function f inverse exists.

Domain of $f^{-1}$ = ( 2, 4, 6, 8 )

Range of $f^{-1}$ = ( 1, 2, 3, 4 )

$f^{-1$ B ---A ⇒⇒

               $f^{-1}$(2) = 1

               $f^{-1}$(4) = 2

               $f^{-1}$(6) = 3

               $f^{-1}$(8) = 4
