Q. sika f(32x3)=2x+3x+4 f\left(\frac{3}{2 x-3}\right)=\frac{2 x+3}{x+4} .\newlinef(1)? f^{\prime}(1) ?
  1. Find Derivative of f: First, let's find the derivative of the function ff with respect to xx.f(32x3)=2x+3x+4f\left(\frac{3}{2x-3}\right)=\frac{2x+3}{x+4}To find f(x)f'(x), we need to differentiate both sides with respect to xx.
  2. Apply Quotient Rule: Differentiate the right side using the quotient rule: (vuuv)/v2(v'u - uv') / v^2 Let u=(2x+3)u = (2x+3) and v=(x+4)v = (x+4) u=2u' = 2 and v=1v' = 1
  3. Calculate f(x)f'(x): Now apply the quotient rule:\newlinef(32x3)=[(x+4)(2)(2x+3)(1)](x+4)2f'\left(\frac{3}{2x-3}\right) = \frac{[(x+4)(2) - (2x+3)(1)]}{(x+4)^2}\newline= 2x+82x3(x+4)2\frac{2x+8 - 2x - 3}{(x+4)^2}\newline= 5(x+4)2\frac{5}{(x+4)^2}
  4. Find xx for f(1)f'(1): We need to find f(1)f'(1), but we have f(32x3)f'\left(\frac{3}{2x-3}\right). So we need to find the xx that makes 32x3\frac{3}{2x-3} equal to 11.\newlineSet 32x3=1\frac{3}{2x-3} = 1 and solve for xx.\newline2x3=32x - 3 = 3\newlinef(1)f'(1)00\newlinef(1)f'(1)11
