Can someone help me please???? I will fan and medal!!

OpenStudy (snowcrystal):

Which equation represents the axis of symmetry of the function y= -2x^2 + 4x -6?

OpenStudy (snowcrystal):

A.) y=1 B.) x=1 C.) x=3 D.) x= -3

OpenStudy (anonymous):

y= ax^2 + bX + c the axis of symmetry of the function would be X= -b/ 2a

OpenStudy (snowcrystal):

im confused

OpenStudy (anonymous):

why in ur function up there what represents a b and c

OpenStudy (anonymous):

what *

OpenStudy (snowcrystal):

-2x^2 =A 4x = B -6 = C

OpenStudy (anonymous):

good but a b and c represent the factories of the element x = only the number

OpenStudy (snowcrystal):

okay can u explain what u mean im a bit confused

OpenStudy (anonymous):

\[aX ^{2} + b X + C = -2 X ^{2} +4 X -6\]

OpenStudy (anonymous):

a= -2 b=4 c= -6

OpenStudy (snowcrystal):

okay

OpenStudy (anonymous):

soo the axis of symmetry of the function X= -b/2a = -4/(2* -2 )

OpenStudy (anonymous):

= 1

OpenStudy (snowcrystal):

so would it be x=1 or y=1

OpenStudy (anonymous):

X= 1

OpenStudy (snowcrystal):

okay thanks for ur help

OpenStudy (anonymous):

any time :)
