Q. Find the derivative of the following function.\newliney=2x2 y=2^{-x^{2}} \newlineAnswer: y= y^{\prime}=
  1. Identify function components: Identify the function and its components.\newlineWe have y=2x2y = 2^{-x^2}, which is an exponential function with a negative quadratic exponent.
  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 2u2^u and the inner function is u=x2u = -x^2.
  3. Differentiate outer function: Differentiate the outer function with respect to uu. The derivative of 2u2^u with respect to uu is (2uln(2))(2^u \cdot \ln(2)), where ln(2)\ln(2) is the natural logarithm of 22.
  4. Differentiate inner function: Differentiate the inner function with respect to xx. The derivative of x2-x^2 with respect to xx is 2x-2x.
  5. Apply chain rule with derivatives: Apply the chain rule using the derivatives from steps 33 and 44.\newliney=ddx[2x2]=(2x2ln(2))(2x)y' = \frac{d}{dx}[2^{-x^2}] = (2^{-x^2} \cdot \ln(2)) \cdot (-2x)
  6. Simplify derivative expression: Simplify the expression for the derivative.\newliney=2x2x2ln(2)y' = -2x \cdot 2^{-x^2} \cdot \ln(2)\newlineThis is the derivative of the function yy with respect to xx.
