Please follow the rules for posting on the board here https://gre.myprepclub.com/forum/rules-for ... -1083.html and how to post a question

here https://gre.myprepclub.com/forum/qq-how-to ... -2357.html

Also I am moving the post under the right section, and not in general quant section. Moreover, the question misses the E answer choice.

It is highly unlikely that this is a GRE question. And if so it is of very poor quality.

The answer is C and D as y is related to square of x in a parabola. A and B are straight lines!

Option C

f(x)=(x+4)^2=x^2+8x+4=0
f'(x)=2x+8=0
x=-4
y=0
=> min at (-4,0)
