Q. Find the derivative of the following function.\newliney=3x24x y=3^{x^{2}-4 x} \newlineAnswer: y= y^{\prime}=
  1. Identify function components: Identify the function and its components.\newlineThe function y=3(x24x)y = 3^{(x^2 - 4x)} is an exponential function with base 33 and exponent x24xx^2 - 4x.
  2. Apply chain rule for derivatives: Apply the chain rule for derivatives. The 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 3u3^u and the inner function is u(x)=x24xu(x) = x^2 - 4x.
  3. Find derivative of outer function: Find the derivative of the outer function with respect to uu. The derivative of 3u3^u with respect to uu is 3uln(3)3^u \cdot \ln(3), where ln(3)\ln(3) is the natural logarithm of 33.
  4. Find derivative of inner function: Find the derivative of the inner function with respect to xx. The derivative of u(x)=x24xu(x) = x^2 - 4x with respect to xx is ddx(x2)ddx(4x)\frac{d}{dx}(x^2) - \frac{d}{dx}(4x), which simplifies to 2x42x - 4.
  5. Apply chain rule: Apply the chain rule.\newlineUsing the chain rule, the derivative of yy with respect to xx is the derivative of the outer function evaluated at the inner function times the derivative of the inner function. This gives us y=(3x24xln(3))(2x4)y' = (3^{x^2 - 4x} \cdot \ln(3)) \cdot (2x - 4).
  6. Simplify expression: Simplify the expression.\newlineWe can simplify the expression for the derivative to y=3(x24x)ln(3)(2x4)y' = 3^{(x^2 - 4x)} \cdot \ln(3) \cdot (2x - 4).
