Question

If f(x) = $\{\begin{array}{cc}\frac{x-2}{3x^2-10x+8};& x\ne 2\\ \frac{1}{2};& x=2\end{array}$, then

यदि f(x) = $\{\begin{array}{cc}\frac{x-2}{3x^2-10x+8};& x\ne 2\\ \frac{1}{2};& x=2\end{array}$, तब

• A. f ′(2) = $-\frac{3}{4}$
• B. f ′(2) = $\frac{1}{2}$
• C. f ′(2) = $-\frac{1}{4}$
• D. f(x) is not differentiable at x = 2
  
  x = 2 पर f(x) अवकलनीय नहीं है

Answer 1

The correct option is A f ′(2) = $-\frac{3}{4}$
