Answer:

The point slope form of the line would be y + 1 = 3(x - 2) and the equation of the line would be y = 3x - 7

Step-by-step explanation:

To find the point-slope form of the line, start with the base form of point-slope form. Then input the point we have and the slope in the appropriate places.

y - y1 = m(x - x1)

y - -1 = 3(x - 2)

y + 1 = 3(x - 2)

Now to find the slope intercept form, you simply need to solve for y.

y + 1 = 3(x - 2)

y + 1 = 3x - 6

y = 3x - 7

The slope would be 1/3 because it’s intersecting line A :)

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

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 $x\in \mathbb{R}$ .
