Would -3,0 be the critical point for f(x)=√(x+3)?
*January 12, 2016*

**Calculus**

Since f(x)=√(x-3) has an absolute minimum of 0 does its critical point exist? I'm really confused because someone mentioned that f(x)=√(x+3) does not have a critical point. Does that mean that if there is an end point there, there can't be a critical point?
