Question

anonymous · Answer

ppp please help me, I have no idea how to do this

anonymous · Answer

Your equation is in the form y=ax^2+bx+c

2=a
24=b
62=c

formula for axis of symmetry is x=-b/2a

x=-24/(2*2)
x=?

anonymous · Answer

x = –6 

 x = 6 

 x = –10 

 x = 10 

these be the possible answers...

And if you do have the time, i would very much appreciate an explanation to the problem ...... Describe the differences between the graph of y = –3(x + 7)2 – 10 and the standard position graph of y = x2.

Did you read my post? All thats left to do is -24/(2*2)

anonymous · Answer

so -6 yea?
