Solution

Para determinar si las funciones son pares o impares, debemos recordar las definiciones:

  • Una función f(x) f(x) es par si f(x)=f(x) f(-x) = f(x) .
  • Una función f(x) f(x) es impar si f(x)=f(x) f(-x) = -f(x) .

Analicemos cada función:

  1. f(x)=sin(x4x2) f(x) = \sin(x^4 - x^2)

    • f(x)=sin((x)4(x)2)=sin(x4x2)=f(x) f(-x) = \sin((-x)^4 - (-x)^2) = \sin(x^4 - x^2) = f(x)
    • Por lo tanto, f(x) f(x) es par.
  2. h(x)=(x3)3 h(x) = (|x| - 3)^3

    • h(x)=(x3)3=(x3)3=h(x) h(-x) = (|-x| - 3)^3 = (|x| - 3)^3 = h(x)
    • Por lo tanto, h(x) h(x) es par.
  3. g(x)=ln(x)+3 g(x) = \ln(|x|) + 3

    • g(x)=ln(x)+3=ln(x)+3=g(x) g(-x) = \ln(|-x|) + 3 = \ln(|x|) + 3 = g(x)
    • Por lo tanto, g(x) g(x) es par.
  4. s(x)=sin3(x) s(x) = \sin^3(x)

    • s(x)=sin3(x)=(sin(x))3=(sin(x))3=sin3(x)=s(x) s(-x) = \sin^3(-x) = (\sin(-x))^3 = (-\sin(x))^3 = -\sin^3(x) = -s(x)
    • Por lo tanto, s(x) s(x) es impar.

Con esta información, podemos concluir que la opción correcta es:

E. f f y h h son pares, s s es impar.
