Question

Identify the vertex and the axis of symmetry of the graph of the function y = 3(x + 2)2 – 3.

vertex: (2, –3); axis of symmetry: x = 2
vertex: (–2, –3); axis of symmetry: x = –2
vertex: (2, 3); axis of symmetry: x = 2
vertex: (–2, 3); axis of symmetry: x = –2

Answer 1

this is a vertex form :
y=a(x-h)^2 +k

with vertex (h,k)

Answer 2

hence the axis of symmetry is x =h

Answer 3

can you answer now?

Answer 4

I dont understand how to write it ?

Answer 5

general form :
y=a(x-h)^2 +k
our case :
y = 3(x + 2)2 – 3
so for us

a = 3
h = -2
k = -3

Answer 6

is the vertex ( 2, -3 )

Answer 7

try again using what i just wrote

Answer 8

I dont understand what x is ?

Answer 9

x is the independent variable ..

given
y=a(x-h)^2 +k
the vertex is (h,k) and axis of symmetry is x =h
