Q. Find the derivative of the following function.y=e−6x2+3xAnswer: y′=
Identify function: Identify the function to differentiate. y=e(−6x2+3x)
Recognize composition: Recognize that this is a composition of functions: the exponential function and a quadratic function. We will use the chain rule to differentiate.The outer function is eu, where u=−6x2+3x.The inner function is u(x)=−6x2+3x.
Derivative of outer function: Find the derivative of the outer function with respect to u. If v=eu, then v′=eu⋅dxdu.
Derivative of inner function: Find the derivative of the inner function with respect to x.u′(x)=dxd(−6x2+3x)=dxd(−6x2)+dxd(3x)=−12x+3.
Apply chain rule: Apply the chain rule: y′=v′⋅u′(x). y′=e(−6x2+3x)⋅(−12x+3).
Simplify derivative: Simplify the expression for the derivative. y′=(−12x+3)⋅e(−6x2+3x).
