Question

I really need to be sure I get a 100 on this:(
What is the axis of symmetry for the graph of y=2x^2-8x+2?

What is the vertex for the graph of
Y-2=-(x+3)^2?

What are the x-intercepts for the graph of y=3(x-2)(x+6)?

PLEASE HELP!

Answer 1

y=2x^2-8x+2
do you know how to complete the square? put in vertex form

vertex form y = a(x-h)^2 + k vertex = (h, k)
axis of symmetry x = h
h= -b/(2a)

Answer 2

What is the vertex for the graph of
Y-2=-(x+3)^2?
rewrite as y =
vertex (h,k)

Answer 3

What are the x-intercepts for the graph of y=3(x-2)(x+6)?
means what are the x values when y = 0
when y = 0 means 3 =0 or (x-2) = 0 or (x + 6) = 0

Answer 4

any questions about my response?

Answer 5

Thank you! I'm just trying to figure it all out
