Notice that the domain of your derivative is
Hi I have a really easy question that I do not understand here.
y = (2sqrt(x))/(1-x)),
and for dy/dx I got (x+1)/(sqrt(x)(1-x)^2)
Here's what I'm confused about,
For what values of x is dy/dx zero.
My answer will be -1 since if the numerator is zero, dy/dx will be zero but the answer says never..
Thank you for your help!!
