Question

Find the inverse function f^-1 for the function f(x) 3x⁷ +4

Answer 1

SOLUTION::

The function f(x)= 3x7 + 4

lets we calculate f(x)=y

then y=  f(x)= 3x7 + 4

y=  3x7 + 4

  3x7= y-4

..................................(1)

the function will be inverse when y=x

this value put on equation (1)

the inverse function of f(x) is

or

ANSWER = OR    BOTH FORM are correct
