Solution
Para determinar si las funciones son pares o impares, debemos recordar las definiciones:
- Una función es par si .
- Una función es impar si .
Analicemos cada función:
-
- Por lo tanto, es par.
-
- Por lo tanto, es par.
-
- Por lo tanto, es par.
-
- Por lo tanto, es impar.
Con esta información, podemos concluir que la opción correcta es:
E. y son pares, es impar.
