Ok so i was wondering if what i am doing is correct, But it gets the wrong minimum point?(adsbygoogle = window.adsbygoogle || []).push({});

So my function is y=|x+4|

1) y^2=x+4

2)2y(dy/dx)=1

3)dy/dx = 1/2y

4)dy/dx = 1/2|x+4|

I set that 0 and get

0=1/(2(|x+4|))

Am i write in thinking this cannot be solved? or missing something?

Thanks
