    Q.

    Write the inverse of this function:

     f(x)=x−8f\left(x\right)=\sqrt{x-8}  

    answer choices

     f−1(x)=x2+8f^{-1}\left(x\right)=x^2+8  

     f−1(x)=x+8f^{-1}\left(x\right)=x+8  

     f−1(x)=x2−8f^{-1}\left(x\right)=x^2-8  

     f−1(x)=x−8f^{-1}\left(x\right)=x-8  

  • Question 7

    Q.

    Write the inverse of this function:

     g(x)=2xg\left(x\right)=\frac{2}{x}  

    answer choices

     g−1(x)=2xg^{-1}\left(x\right)=\frac{2}{x}  

     g−1(x)=2xg^{-1}\left(x\right)=2x  

     g−1(x)=−2xg^{-1}\left(x\right)=-\frac{2}{x}  

     g−1(x)=−2xg^{-1}\left(x\right)=-2x

    Q.

    Write the inverse of the function:

     h(x)=x2−9h\left(x\right)=x^2-9  

    answer choices

     h−1(x)=±x+9h^{-1}\left(x\right)=\pm\sqrt{x+9}  

     h−1(x)=x+9h^{-1}\left(x\right)=\sqrt{x+9}  

     h−1(x)=±x−9h^{-1}\left(x\right)=\pm\sqrt{x-9}  

     h−1(x)=−x+9h^{-1}\left(x\right)=-\sqrt{x+9}

    Q.

    Write the inverse of the function:

     f(x)=3x−7f\left(x\right)=3x-7  

    answer choices

     f−1(x)=x+73f^{-1}\left(x\right)=\frac{x+7}{3}  

     f−1(x)=x−73f^{-1}\left(x\right)=\frac{x-7}{3}  

     f−1(x)=3x+7f^{-1}\left(x\right)=3x+7  

     f−1(x)=3x−7f^{-1}\left(x\right)=3x-7  

  • Question 10

    Q.

    Write the inverse of the function:

     n(x)=2x−55n\left(x\right)=\frac{2x-5}{5}  

    answer choices

     n−1(x)=5x+52n^{-1}\left(x\right)=\frac{5x+5}{2}  

     n−1(x)=5x+5n^{-1}\left(x\right)=5x+5  

     n−1(x)=5x−52n^{-1}\left(x\right)=\frac{5x-5}{2}  

     n−1(x)=2x−25n^{-1}\left(x\right)=\frac{2x-2}{5}  

  • Question 11

    Q.

    Write the inverse of the function:

     m(x)=5+x2m\left(x\right)=5+x^2  

    answer choices

     m−1(x)=±x−5m^{-1}\left(x\right)=\pm\sqrt{x-5}  

     m−1(x)=−x−5m^{-1}\left(x\right)=-\sqrt{x-5}  

     m−1(x)=±x+5m^{-1}\left(x\right)=\pm\sqrt{x+5}  

     m−1(x)=x−5m^{-1}\left(x\right)=\sqrt{x-5}

    Q.

    Write the inverse of the function:

     b(x)=4x−9b\left(x\right)=\frac{4}{x}-9  

    answer choices

     b−1(x)=4x+9b^{-1}\left(x\right)=\frac{4}{x+9}  

     b−1(x)=4x−9b^{-1}\left(x\right)=\frac{4}{x-9}  

     b−1(x)=−4x+9b^{-1}\left(x\right)=-\frac{4}{x+9}  

     b−1(x)=4x+36b^{-1}\left(x\right)=4x+36
