The graphs are the shame shape but what is the equation of the red line?

Answer:
A
Step-by-step explanation:
Since the shape and vertex x coordinate of both graphs are the same, the only difference is the vertical displacement. Since the blue graph is 4 above the origin and the red graph is 1 above the origin, its graph is:
[tex]g(x)=1-x^2[/tex]
Hence, the correct answer is choice A. Hope this helps!
