Q. Find the derivative of the following function.\newliney=9x2 y=9^{-x^{2}} \newlineAnswer: y= y^{\prime}=
  1. Identify function: Identify the function to differentiate.\newlineWe have y=9(x2)y = 9^{(-x^2)}. This is an exponential function with a base of 99 and an exponent of x2-x^2.
  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. Here, the outer function is 9u9^u and the inner function is u=x2u = -x^2.
  3. Differentiate outer function: Differentiate the outer function with respect to the inner function uu. The derivative of 9u9^u with respect to uu is 9uln(9)9^u \cdot \ln(9), where ln(9)\ln(9) is the natural logarithm of 99.
  4. Differentiate inner function: Differentiate the inner function with respect to xx. The derivative of u=x2u = -x^2 with respect to xx is 2x-2x.
  5. Apply chain rule: Apply the chain rule by multiplying the derivatives from steps 33 and 44.\newlineThe derivative of yy with respect to xx is (9x2ln(9))(2x)(9^{-x^2} \cdot \ln(9)) \cdot (-2x).
  6. Simplify expression: Simplify the expression.\newliney=2x9x2ln(9)y' = -2x \cdot 9^{-x^2} \cdot \ln(9).
