	Các bình luận về: 15. Cho hàm số \(f\left( x \right)\) xác định và liên tục trên \(\mathbb{R}\backslash \left\{ { \pm \sqrt 3 } \right\}\), thỏa mãn \(1 &#8211; {x^3} = 2{x^2}f\left( x \right) + x{f^2}\left( x \right) &#8211; f&#8217;\left( x \right)\) và \(f\left( 1 \right) = 0\). Hàm số \(g\left( x \right) = {\left[ {f\left( {2x &#8211; 1} \right)} \right]^2}\) có bao nhiêu điểm cực tiểu ?	</title>
