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

a(x-h)^2+k

does that help

Answer 2

not really

Answer 3

y = 3(x + 2)^2 – 3.
y = a(x - h)^2 + k

Answer 4

vertex is (h,k)!

Answer 5

thanks ! i get it
