Q. Find the derivative of the following function.\newliney=e6x2+9x y=e^{-6 x^{2}+9 x} \newlineAnswer: y= y^{\prime}=
  1. Identify function: Identify the function to differentiate.\newliney=e(6x2+9x)y = e^{(-6x^2 + 9x)}
  2. Recognize composition: Recognize that this is a composition of functions: the exponential function and a quadratic function. The outer function is eue^u, and the inner function is u(x)=6x2+9xu(x) = -6x^2 + 9x.
  3. Find derivative outer function: Find the derivative of the outer function with respect to uu, where u=6x2+9xu = -6x^2 + 9x.\newlineIf v=euv = e^u, then v=eududxv' = e^u \cdot \frac{du}{dx}.
  4. Find derivative inner function: Find the derivative of the inner function u(x)=6x2+9xu(x) = -6x^2 + 9x with respect to xx.u(x)=ddx(6x2+9x)=ddx(6x2)+ddx(9x)=12x+9.u'(x) = \frac{d}{dx}(-6x^2 + 9x) = \frac{d}{dx}(-6x^2) + \frac{d}{dx}(9x) = -12x + 9.
  5. Apply chain rule: Apply the chain rule, which states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function.\newliney=euu(x)y' = e^u \cdot u'(x) where u=6x2+9xu = -6x^2 + 9x and u(x)=12x+9u'(x) = -12x + 9.
  6. Substitute into derivative: Substitute uu and u(x)u'(x) into the derivative of the outer function.\newliney=e(6x2+9x)(12x+9).y' = e^{(-6x^2 + 9x)} * (-12x + 9).
  7. Simplify final answer: Simplify the expression to get the final answer.\newliney=(12x+9)e(6x2+9x).y' = (-12x + 9)e^{(-6x^2 + 9x)}.
