Answer:
F(x²) = x⁴ + 2
Step-by-step explanation:
Given: function F(x) = x² + 2
To find: F(x²)
=================
To find F(x²) we simply replace x with x² in the given function:
- F(x²)= (x²)² + 2= x⁴ + 2
- F(x²) = x⁴ + 2
Hola!
x = 7 , x = -7
Explicación:
Comienza restando 15 en cada lado:

Usted obtiene:

Ahora divide ambos lados por 2:

Usted obtiene:

Como la ecuación está al cuadrado, tendrás que hacer:

que te da:
