Solution

Para encontrar la función inversa de f(x)=ex2 f(x) = e^{-x^2} , sigamos los siguientes pasos:

  1. Definir la función y la variable: y=f(x)=ex2 y = f(x) = e^{-x^2}

  2. Intercambiar x x y y y : x=ey2 x = e^{-y^2}

  3. Resolver para y y : ln(x)=y2 \ln(x) = -y^2 ln(x)=y2 -\ln(x) = y^2 y=±ln(x) y = \pm \sqrt{-\ln(x)}

  4. Determinar el dominio de la función inversa: Dado que f(x) f(x) mapea R \mathbb{R} a (0,1) (0,1) , la función inversa debe tener dominio en (0,1) (0,1) .

  5. Seleccionar la rama correcta: Para que y y sea una función, debemos elegir una sola rama. Generalmente, se elige la rama positiva: y=ln(x) y = \sqrt{-\ln(x)}

Por lo tanto, la función inversa es: f1(x)=ln(x) f^{-1}(x) = \sqrt{-\ln(x)} con dominio (0,1) (0,1) .

La respuesta correcta es: c. f1(x) f^{-1}(x) no existe
