Thread: Minima, maxima of function View Single Post
 P: 365 How will I find minima,maxima or both of one function (if they exist)? For example: $$f(x)=x^2-3x+2$$; $$f(x)=x^2-2x-x+2$$; $$f(x)=x(x-2)-(x-2)$$; $$f(x)=(x-2)(x-1)$$ x1,2=1,2 Those are the zeroes of the function. But how will I find the critical points (minima,maxima) of the function if $x \in \mathbb{R}$
