f(x)=4 hallar el dominio, codominio, ceros o raices, vertices, asintotas, tabla de valores, graficas, identificar el tipo de fun
nekit [7.7K]

Answer:

Tipo de función: Función Constante o Función Polinómica de Orden Cero

Dominio: Dom \{f(x)\} = \mathbb{R}

Codominio: Ran \{f(x)\} = 4

Asíntota: y = 4

Raíces: No tiene.

Vértices: No tiene.

La tabla de valores y el gráfico se encuentran adjuntos al fondo.

Step-by-step explanation:

Sea f(x) = 4, el cual representa a una Función Constante o Función Polinómica de Orden Cero, cuyos dominio y codominio son Dom \{f(x)\} = \mathbb{R} y Ran \{f(x)\} = 4. No tiene vértices. Esta función tiene una asíntota horizontal coincidente con la función (y = 4) y carece de raíces al ser f(x) \ne 0 para todo x\in \mathbb{R}.

Finalmente, agregamos una tabla de valores y la gráfica asociada a la función:

x         -2         -1         0         1          2

y         4          4         4         4         4
