Paso 5.3.2

Evalúa $f (x^{5} - 35 x^{4} + 490 x^{3} - 3430 x^{2} + 12005 x - 16807)$ mediante la sustitución del valor de $f^{- 1}$ en $f$ .

$f (x^{5} - 35 x^{4} + 490 x^{3} - 3430 x^{2} + 12005 x - 16807) = {(x^{5} - 35 x^{4} + 490 x^{3} - 3430 x^{2} + 12005 x - 16807)}^{\frac{1}{5}} + 7$

Paso 5.4

Como $f^{- 1} (f (x)) = x$ y $f (f^{- 1} (x)) = x$ , entonces $f^{- 1} (x) = x^{5} - 35 x^{4} + 490 x^{3} - 3430 x^{2} + 12005 x - 16807$ es la inversa de $f (x) = x^{\frac{1}{5}} + 7$ .

$f^{- 1} (x) = x^{5} - 35 x^{4} + 490 x^{3} - 3430 x^{2} + 12005 x - 16807$
