Q. Find the derivative of the following function.y=e9x3−2x2Answer: y′=
Identify Function: Identify the function and its components.The function is y=e9x3−2x2. This is an exponential function where the exponent is a polynomial.
Apply Chain Rule: Apply the chain rule for differentiation.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 eu and the inner function is u=9x3−2x2.
Differentiate Outer Function: Differentiate the outer function with respect to the inner function u. The derivative of eu with respect to u is eu. So, (dud)(eu)=eu.
Differentiate Inner Function: Differentiate the inner function u=9x3−2x2 with respect to x. Using the power rule, the derivative of 9x3 is 27x2 and the derivative of −2x2 is −4x. So, (d/dx)(9x3−2x2)=27x2−4x.
Combine Derivatives: Combine the derivatives using the chain rule.The derivative of y with respect to x is the derivative of the outer function evaluated at the inner function times the derivative of the inner function.So, y′=e(9x3−2x2)⋅(27x2−4x).
