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}

What is the length of the hypotenuse?
Rainbow [258]

Answer:

Hello! answer: 58

Step-by-step explanation:

40 × 40 = 1600

1600 + 1764 = 3364

√3364 = 58

58 × 58 = 3364 therefore c = 58 Hope that helps!
