Identify Function: Identify the function that needs differentiation. The function is f(x)=xex, which is a quotient of two functions.
Use Quotient Rule: Recognize that we need to use the quotient rule for differentiation because we have a function in the form of h(x)g(x), where g(x)=ex and h(x)=x.
Recall Quotient Rule: Recall the quotient rule: (dxd)[h(x)g(x)]=[h(x)]2g′(x)h(x)−g(x)h′(x). We will apply this rule to find the derivative of f(x).
Differentiate Numerator: Differentiate the numerator g(x)=ex. The derivative of ex with respect to x is ex.
Differentiate Denominator: Differentiate the denominator h(x)=x. The derivative of x with respect to x is 1.
Apply Quotient Rule: Apply the quotient rule using the derivatives from the previous steps. The derivative of f(x) is f′(x)=x2ex⋅1−ex⋅1.
Simplify Expression: Simplify the expression. The derivative of f(x) simplifies to f′(x)=x2ex−ex, which further simplifies to f′(x)=x20.
