Answer:

Option B

Explanation:

Rewrite each of the options given to us in standard form. That way we can identify the parabola properties of each -


Standard Form = 4\cdot \:2\left(y-\left(-9\right)\right)=\left(x-8\right)^2,\\\left(h,\:k\right)=\left(8,\:-9\right),\:p=2\\-----------------\\Standard Form = 4\cdot \:2\left(y-8\right)=\left(x-\left(-9\right)\right)^2,\\\left(h,\:k\right)=\left(-9,\:8\right),\:p=2

Right away you can tell that the second option is correct. The vertex is known to be ( - 9, 8 ) and extends at an exponential rate of 2. This is our solution, Option b!
