Q. For the following equation, find f′(x).f(x)=−8x3+xAnswer: f′(x)=
Apply Power Rule: To find the derivative of the function f(x)=−8x3+x, we will apply the power rule for differentiation. The power rule states that the derivative of xn with respect to x is n⋅x(n−1).
Differentiate −8x3: Differentiate the term −8x3. Using the power rule, the derivative of −8x3 is −8×3×x(3−1)=−24x2.
Differentiate x: Differentiate the term x. The derivative of x with respect to x is 1, since the power rule gives us 1×x1−1=1×x0=1.
Combine Derivatives: Combine the derivatives of both terms to get the derivative of the entire function. Therefore, f′(x)=−24x2+1.
