VI. Composicion de funciones: 1. Para f(x) = Vx - 1;g(x) = 2x2 - 7. Halla: a. (f . g) (x) b. (go f ) (x) 2. Sif(x) = resulta de (f . g)(x); entonces indique las funciones. 3. Dado que las funciones f y g se presentan en las siguientes tablas. 0 2 3 X 2 5 7 f(x) 3 2 5 gx 10 3 2 Entonces, calcula: a. (fog) (2) b. (g . f) (-1) VII. Escriba en forma estandar ( a(x - h)2 + k ) y determina el valor maximo o minimo: a. f(x) =3x2 - 12x + 23 b. g(x) = -2x2 + 4x - 5 C. h(x) = 4x2 - 8x + 7 VIII. Resuelva: a. Use la division larga e indique el cociente y residuo: a. 4x3-2x2+ 2x-1 2x-3 Modificado y Recomendaciones por Dra. Magda I. Flores Perez y Prof. Aida L. Gonzalez (abr. 2021) b. 8x4+6x2-3x+1 2x2-x+2 2. Use la division sintetica e indique el cociente y residuo: 4x + 3x - 5 a. x - 7 5x3 + 3x-2 b. x+3 3 + 5 C. x+ 2 IX. Expresa los siguientes ejercicios en la forma a + bi: 1. (3 + 51)(-4+7i) 2. (2 - 91) (2 + 9i) 3. 5+i -2i 3+4i 4. -2+3i 5. (1 + 3i) -1 X. Resuelva los siguientes ejercicios: 1. P(x) = 3x5 + 5x4 - 4x3 + 7x+3 a. Halla el cociente y residuo con el divisor x + 2 b. Utilice el Teorema de Residuo para hallar P (-2)
