2x - x = 7 - 2
x = 5
Answer:

Step-by-step explanation:
The equation of a parabola: y = ax²
The larger the value of |a|, the narrower the parabola.
We have the following coefficients a:

We arrange the coefficients from the smallest to the largest:

Therefore you have the answer:

B) y=34.84x-2054 I believe that is the right answer
