Q. Find the derivative of the following function.\newliney=e3x37x2 y=e^{-3 x^{3}-7 x^{2}} \newlineAnswer: y= y^{\prime}=
  1. Identify function: Identify the function to differentiate.\newlineThe function given is y=e(3x37x2)y = e^{(-3x^3 - 7x^2)}. We need to find the derivative of this function with respect to xx.
  2. Apply chain rule: Apply the chain rule for differentiation.\newlineThe chain rule 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. In this case, the outer function is eue^u and the inner function is u=3x37x2u = -3x^3 - 7x^2.
  3. Differentiate outer function: Differentiate the outer function with respect to the inner function uu. The derivative of eue^u with respect to uu is eue^u. So, the derivative of the outer function is e(3x37x2)e^{(-3x^3 - 7x^2)}.
  4. Differentiate inner function: Differentiate the inner function u=3x37x2u = -3x^3 - 7x^2 with respect to xx. The derivative of 3x3-3x^3 with respect to xx is 9x2-9x^2, and the derivative of 7x2-7x^2 with respect to xx is 14x-14x. Therefore, the derivative of the inner function is 9x214x-9x^2 - 14x.
  5. Apply chain rule multiplication: Apply the chain rule by multiplying the derivative of the outer function by the derivative of the inner function.\newlineThe derivative of the outer function is e(3x37x2)e^{(-3x^3 - 7x^2)}, and the derivative of the inner function is 9x214x-9x^2 - 14x. Multiplying these together gives us the derivative of yy with respect to xx.\newliney=e(3x37x2)×(9x214x)y' = e^{(-3x^3 - 7x^2)} \times (-9x^2 - 14x)
  6. Simplify derivative: Simplify the expression for the derivative.\newliney=9x2e(3x37x2)14xe(3x37x2)y' = -9x^2 \cdot e^{(-3x^3 - 7x^2)} - 14x \cdot e^{(-3x^3 - 7x^2)}\newlineThis is the final form of the derivative.
