State if the given functions are inverses.

1 pt DOK: 2

$f (x) = \frac{8 + x}{4}$ , $g (x) = 4 x - 8$

Yes

1 pt DOK: 2

$f (x) = 4 - \frac{1}{4} x$ , $g (x) = - \frac{2}{3} - \frac{4}{3}$

Yes

1 pt DOK: 2

$f (x) = \frac{3 x + 9}{8}$

$f^{- 1} (x) = \frac{- 25 - 8 x}{5}$

$f^{- 1} (x) = x - 4$

$f^{- 1} (x) = \frac{- 3 + 2 x}{3}$

$f^{- 1} (x) = \frac{- 9 + 8 x}{3}$

1 pt DOK: 2

$h (x) = \sqrt[3]{- x - 1}$

$h^{- 1} (x) = - x^{3} - 2$

$h^{- 1} (x) = - x^{3} - 1$

$h^{- 1} (x) = \sqrt[3]{\frac{- x - 3}{2}}$

$h^{- 1} (x) = \sqrt[3]{- x + 2}$
