Answer:
Step-by-step explanation:
General equation of a parabola that opens up is 
, a>0
So equation becomes 
which implies option A and option B can never be true for this parabola.
Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.
So, the equation of parabola will be of the form 
Hence, option 4 that is is correct.
