Ecuaciones cadraticas en forma estandar

Ecuacion cuadratica en forma estandar

 

Y= a(x-h)"+k

 

Donde (a,h,k) segun sus valores la grafica se movera hacia arriba o abajo, a la derecha o a la izquierda y tambien se podra ensanchar o adelgazar.

 

Ahora pondremos en practica la forma estandar en:

 

Y= 3x"

 

a= 3            x=0        k=0

 

Sustituir y  tabular

 

3(-3)"= 27

3(-2)"= 12

3(-1)"= 3

3(0)"= 0

3(1)"= 3

3(2)"= 12

3(3)"= 27

 

                                                                               X | Y

                                                                               -3 | 27

                                                                               -2 | 12

                                                                               -1 | 3

                                                                                0 | 0

                                                                                1 | 3

                                                                                2 | 12

                                                                                3 | 27
