identify the vertex and the axis of symmetry of the graph for the function y=3(x+2)^2
a.vertex(2,-3
axis of symmetry x=2
b.vertex(-2,-3)
axis of symmetry x=-2
c.vertex(2,3)
axis of symmetry x=2
d.vertex(-2,3)
axis of symmetry x=-2

identify the maximum or minimum value and the domain and range of the graph of the function y=2(x-3)^2-4.
a.minimum value -4
domain all real numbers
range all real numbers_>_-4
b.max value 4
domain all real numbers
range all real numbers_<_4
c. max value -4
domain all real numbers_<_-4
range all real numbers
d. minimum value 4
domain all real numbers_>_4
range all real numbers

please i need some help guys thanks

• URGENT ALGEBRA 2 - ,

if you know that

y = a(x-h)^2 + k

has axis of symmetry at x=h
and vertex at (h,k)

all polynomials have domain of all reals numbers

you are home free.

im not sure steve should be able to give you the answer im stumped on this one to ray

identify the vertex and the axis of symmetry of the graph for the function y=3(x+2)^2

vertex at (-2,0)
axis: x = -2
If it was y = 3 + (x+2)^2
then the vertex is at (-2,3)

identify the maximum or minimum value and the domain and range of the graph of the function y=2(x-3)^2-4.
vertex at (3,-4)
axis: x=3
minimum at vertex: y = -4
domain all reals
range: all reals >= -4 (where the vertex is)
