Q. Find the derivative of the following function.\newliney=38x2 y=3^{-8 x^{2}} \newlineAnswer: y= y^{\prime}=
  1. Identify Function Components: Identify the function and its components.\newlineWe have y=38x2y = 3^{-8x^{2}}. This is an exponential function where the base is a constant (33) and the exponent is a function of xx (8x2-8x^{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.\newlineIn this case, the outer function is f(u)=3uf(u) = 3^u and the inner function is u(x)=8x2u(x) = -8x^{2}.
  3. Differentiate Outer Function: Differentiate the outer function with respect to uu. The derivative of f(u)=3uf(u) = 3^u with respect to uu is f(u)=3uln(3)f'(u) = 3^u \cdot \ln(3), where ln(3)\ln(3) is the natural logarithm of 33.
  4. Differentiate Inner Function: Differentiate the inner function with respect to xx. The derivative of u(x)=8x2u(x) = -8x^{2} with respect to xx is u(x)=ddx(8x2)=16xu'(x) = \frac{d}{dx}(-8x^{2}) = -16x.
  5. Apply Chain Rule with Derivatives: Apply the chain rule using the derivatives from steps 33 and 44.\newliney=f(u(x))u(x)=(38x2ln(3))(16x)y' = f'(u(x)) \cdot u'(x) = (3^{-8x^{2}} \cdot \ln(3)) \cdot (-16x).
  6. Simplify Derivative: Simplify the expression for the derivative.\newliney=16x38x2ln(3)y' = -16x \cdot 3^{-8x^{2}} \cdot \ln(3).\newlineThis is the derivative of the function yy with respect to xx.
