If $f^{-1}(x)$ is the inverse of $f(x)$ , then by definition of inverse functions,

$\left(f\circ f^{-1}\right)(x) = f\left(f^{-1}(x)\right) = x$

Given $f(x) = 2x-8$ , the inverse, if its exists, satisfies the equation above. Evaluate $f$ at the inverse, we have

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

Solve for the inverse:

$2 f^{-1}(x) - 8 = x$

$2 f^{-1}(x) = x + 8$

$\boxed{f^{-1}(x) = \dfrac12 x + 4}$

Given $g(x) = \frac13 x + 5$ , we do the same thing as before to find its inverse.

$g\left(g^{-1}(x)\right) = \dfrac13 g^{-1}(x) + 5 = x \implies \boxed{g^{-1}(x) = 3x - 15}$

Answer:

85751

Step-by-step explanation:

81924

+ 3827

_______

85751

- Start from the right side, 4 + 7 = 11, but the 1 is carried over

- 2 + 2 + 1 = 5

- 9 + 8 = 17, but the 1 is carried over

- 1 + 3 + 1 = 5

- 8 + 0 = 8

Thus, the answer becomes 85751.
