Answer:
A
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:
![g(x)=1-x^2](https://img.qammunity.org/2021/formulas/mathematics/college/txj0ew8ufsbgltlwkqj1480jbmos51nwa9.png)
