Q. For the following equation, evaluate f(2) f^{\prime}(2) .\newlinef(x)=2x3+2 f(x)=-2 x^{3}+2 \newlineAnswer:
  1. Identify Function & Derivative: Identify the function and the derivative to be calculated.\newlineWe are given the function f(x)=2x3+2f(x) = -2x^3 + 2 and we need to find its derivative at x=2x = 2, which is denoted by f(2)f'(2).
  2. Calculate Derivative of Function: Calculate the derivative of the function f(x)f(x). The derivative of f(x)=2x3+2f(x) = -2x^3 + 2 with respect to xx is f(x)=6x2f'(x) = -6x^2. This is obtained by applying the power rule of differentiation, which states that the derivative of xnx^n is nx(n1)n\cdot x^{(n-1)}.
  3. Evaluate Derivative at x=2x = 2: Evaluate the derivative at x=2x = 2. Substitute x=2x = 2 into the derivative f(x)=6x2f'(x) = -6x^2 to find f(2)f'(2). f(2)=6(2)2f'(2) = -6*(2)^2 f(2)=64f'(2) = -6*4 f(2)=24f'(2) = -24
