Q. Given the function f(x)=(−2x2+6x)6, find f′(x) in any form.Answer: f′(x)=
Identify Functions: To find the derivative of the function f(x)=(−2x2+6x)6, we will use the chain rule. 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.
Find Derivatives: First, let's identify the outer function and the inner function. The outer function is g(u)=u6 and the inner function is u(x)=−2x2+6x. We will need to find the derivative of both functions.
Apply Chain Rule: The derivative of the outer function g(u)=u6 with respect to u is g′(u)=6u5.
Substitute Derivatives: The derivative of the inner function u(x)=−2x2+6x with respect to x is u′(x)=−4x+6.
Simplify Expression: Now, we apply the chain rule: f′(x)=g′(u(x))⋅u′(x). Substituting the derivatives we found, we get f′(x)=6(−2x2+6x)5⋅(−4x+6).
Final Derivative Form: Simplify the expression to get the final form of the derivative: f′(x)=6(−2x2+6x)5∗(−4x+6). This is the derivative of the function f(x) in any form.
