the graph below have the same shape. what is the equation of the blue graph

Option: B is the correct answer.
The equation of blue graph is:
B. [tex]y=(x+4)^2-3[/tex]
We could clearly observe from the graph that the vertex of the blue graph is:
(-4,-3)
Also from the figure we could see that the parabola is a upward open parabola.Hence, the general equation of an upward open parabola is given by:
[tex]y=a(x-h)^2+k[/tex]
where (h,k) denote the vertex of the parabola.
Hence, we have: (h,k)=(-4,-3)
i.e. h= -4 and k= -3
Hence, the equation of blue graph is:
[tex]y=(x-(-4))^2-3\\\\y=(x+4)^2-3[/tex]
