Q. Given the function f(x)=x322x3 f(x)=\frac{x^{3}-2}{2 x-3} , find f(x) f^{\prime}(x) in simplified form.\newlineAnswer: f(x)= f^{\prime}(x)=
  1. Quotient Rule Explanation: To find the derivative of the function f(x)=x322x3f(x) = \frac{x^3 - 2}{2x - 3}, we will use the quotient rule. The 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 f(x)f'(x) is given by v(x)u(x)u(x)v(x)(v(x))2\frac{v(x) \cdot u'(x) - u(x) \cdot v'(x)}{(v(x))^2}. Here, u(x)=x32u(x) = x^3 - 2 and v(x)=2x3v(x) = 2x - 3.
  2. Derivative of u(x)u(x): First, we need to find the derivative of u(x)=x32u(x) = x^3 - 2. The derivative of x3x^3 is 3x23x^2, and the derivative of a constant is 00. Therefore, u(x)=3x2u'(x) = 3x^2.
  3. Derivative of v(x)v(x): Next, we need to find the derivative of v(x)=2x3v(x) = 2x - 3. The derivative of 2x2x is 22, and the derivative of a constant is 00. Therefore, v(x)=2v'(x) = 2.
  4. Applying Quotient Rule: Now we apply the quotient rule. We have u(x)=3x2u'(x) = 3x^2 and v(x)=2v'(x) = 2, so we plug these into the quotient rule formula:\newlinef(x)=(2x3)(3x2)(x32)(2)(2x3)2f'(x) = \frac{(2x - 3) * (3x^2) - (x^3 - 2) * (2)}{(2x - 3)^2}.\newlineLet's simplify this expression step by step.
  5. Multiplying (2x3)(2x - 3) by 3x23x^2: First, we multiply (2x3)(2x - 3) by 3x23x^2 to get 6x39x26x^3 - 9x^2.
  6. Multiplying (x32)(x^3 - 2) by 22: Next, we multiply (x32)(x^3 - 2) by 22 to get 2x342x^3 - 4.
  7. Subtracting Products: Now we subtract the second product from the first product to get the numerator of the derivative:\newline(6x39x2)(2x34)=6x39x22x3+4(6x^3 - 9x^2) - (2x^3 - 4) = 6x^3 - 9x^2 - 2x^3 + 4.
  8. Combining Like Terms: Simplify the numerator by combining like terms:\newline6x32x39x2+4=4x39x2+46x^3 - 2x^3 - 9x^2 + 4 = 4x^3 - 9x^2 + 4.
  9. Final Derivative: Now we have the simplified numerator, and we place it over the square of the denominator:\newlinef(x)=4x39x2+4(2x3)2f'(x) = \frac{4x^3 - 9x^2 + 4}{(2x - 3)^2}.\newlineThis is the derivative of the function in simplified form.
