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 \(D=\dfrac{E}{0.92086}\)
