Q. For the following equation, evaluate f′(2).f(x)=−2x3+2Answer:
Identify Function & Derivative: Identify the function and the derivative to be calculated.We are given the function f(x)=−2x3+2 and we need to find its derivative at x=2, which is denoted by f′(2).
Calculate Derivative of Function: Calculate the derivative of the function f(x). The derivative of f(x)=−2x3+2 with respect to x is f′(x)=−6x2. This is obtained by applying the power rule of differentiation, which states that the derivative of xn is n⋅x(n−1).
Evaluate Derivative at x=2: Evaluate the derivative at x=2. Substitute x=2 into the derivative f′(x)=−6x2 to find f′(2). f′(2)=−6∗(2)2f′(2)=−6∗4f′(2)=−24
