One third (or 1/3 ) is the correct answer
Equation of parabola is
.
<u>Step-by-step explanation:</u>
The vertex form of the parabola is given as, ![y=a(x-h)^{2}+k](https://tex.z-dn.net/?f=y%3Da%28x-h%29%5E%7B2%7D%2Bk)
where (h,k) is the vertex of the parabola.
If the parabola must be symmetric about x = -10 then the axis of symmetry must be x = -10.
To execute this, h should be -10, and it was plugged in the vertex form of the parabola, a and k may be any real number.
So the equation can be written as, ![y=(x+10)^{2}](https://tex.z-dn.net/?f=y%3D%28x%2B10%29%5E%7B2%7D)
