Question

If for a particular one-to-one function  f left parenthesis 2 right parenthesis equals 4 and  f left parenthesis 5 right parenthesis equals 12, what are the corresponding input and output values for the inverse function?

  1. f to the power of negative 1 end exponent left parenthesis 2 right parenthesis equals 4 comma space f to the power of negative 1 end exponent left parenthesis 5 right parenthesis space equals space 12
  2. f to the power of negative 1 end exponent left parenthesis 4 right parenthesis equals 0 comma space f to the power of negative 1 end exponent left parenthesis 5 right parenthesis space equals space 5
  3. f to the power of negative 1 end exponent left parenthesis 4 right parenthesis equals 2 comma space f to the power of negative 1 end exponent left parenthesis 12 right parenthesis space equals space 5
  4. f to the power of negative 1 end exponent left parenthesis 4 right parenthesis equals 2 comma f to the power of negative 1 end exponent left parenthesis 12 right parenthesis space equals space 5

hintHint:

We are given two one-two-one functions. We have to find the input and output values of the inverse of the functions.

The correct answer is: f to the power of negative 1 end exponent left parenthesis 4 right parenthesis equals 2 comma space f to the power of negative 1 end exponent left parenthesis 12 right parenthesis space equals space 5


    We are given two functions. One to one functions means, for every element in first set there is only one element in the second set.
    To solve this question we will take the inverse of both the sides of the function.
    Taking the inverse we can write.
    iven  f left parenthesis 2 right parenthesis space equals space 4 not stretchy rightwards double arrow 2 space equals space f to the power of negative 1 end exponent left parenthesis 4 right parenthesis
    And for  f left parenthesis 5 right parenthesis equals 12 not stretchy rightwards double arrow 5 equals f to the power of negative 1 end exponent left parenthesis 12 right parenthesis
    When we take the inverse, the input of the function becomes the output and output of the function becomes the input.
    We will find the option that matches the above values.

    For such questions, we should know the properties of inverse function.
