FNGR 2 | Lesson 5 | Practice (Writing Inverse Equations) Solutions

1.  \(f^{-1}(x)=\dfrac{x+2}3\)

2.  \(f^{-1}(x) = -\dfrac12 x + 1\)

3.  \(f^{-1}(x) = \sqrt[3]x\)

4.  There is no inverse.

5.  \(f^{-1}(x) =\sqrt{x+2}\)  since there is a domain restriction in the function.

6.  \(F = \dfrac{9C}5 + 32\)  and  \(C = \dfrac59 (F-32)\)

7.  \(E=0.92086D\)  and  \(D=\dfrac{E}{0.92086}\)
