Q. Given the function f(x)=x34x3 f(x)=\frac{x}{3-4 x^{3}} , find f(x) f^{\prime}(x) in simplified form.\newlineAnswer: f(x)= f^{\prime}(x)=
  1. Identify Function: Identify the function that needs to be differentiated.\newlineThe function given is f(x)=x34x3f(x) = \frac{x}{3-4x^3}. We need to find its derivative, which is denoted by f(x)f'(x).
  2. Apply Quotient Rule: Apply the quotient rule for differentiation.\newlineThe quotient rule states that if we have a function that is the quotient of two functions, u(x)v(x)\frac{u(x)}{v(x)}, then its derivative is given by v(x)u(x)u(x)v(x)(v(x))2\frac{v(x)u'(x) - u(x)v'(x)}{(v(x))^2}. Here, u(x)=xu(x) = x and v(x)=34x3v(x) = 3 - 4x^3.
  3. Differentiate u(x)u(x): Differentiate u(x)u(x) with respect to xx. The derivative of u(x)=xu(x) = x with respect to xx is u(x)=1u'(x) = 1.
  4. Differentiate v(x)v(x): Differentiate v(x)v(x) with respect to xx. The derivative of v(x)=34x3v(x) = 3 - 4x^3 with respect to xx is v(x)=12x2v'(x) = -12x^2.
  5. Substitute into Formula: Substitute u(x)u(x), u(x)u'(x), v(x)v(x), and v(x)v'(x) into the quotient rule formula.\newlineUsing the quotient rule, we get f(x)=(34x3)(1)(x)(12x2)(34x3)2f'(x) = \frac{(3 - 4x^3)(1) - (x)(-12x^2)}{(3 - 4x^3)^2}.
  6. Simplify Expression: Simplify the expression.\newlineSimplify the numerator: (34x3)(1)(x)(12x2)=34x3+12x3(3 - 4x^3)(1) - (x)(-12x^2) = 3 - 4x^3 + 12x^3.\newlineCombine like terms: 3+8x33 + 8x^3.\newlineNow, f(x)=3+8x3(34x3)2f'(x) = \frac{3 + 8x^3}{(3 - 4x^3)^2}.
