Quotient Rule Explanation: To find the derivative of the function f(x)=exx2, we will use the quotient rule. The quotient rule states that if we have a function that is the quotient of two functions, v(x)u(x), then its derivative is given by (v(x))2u′(x)v(x)−u(x)v′(x). Here, u(x)=x2 and v(x)=ex.
Derivative of u(x): First, we need to find the derivative of u(x)=x2. The derivative of x2 with respect to x is 2x.
Derivative of v(x): Next, we need to find the derivative of v(x)=ex. The derivative of ex with respect to x is ex.
Applying Quotient Rule: Now we apply the quotient rule. The derivative of f(x) is given by (v(x))2u′(x)v(x)−u(x)v′(x). Substituting u′(x)=2x, v(x)=ex, and v′(x)=ex, we get:f′(x)=(ex)22x⋅ex−x2⋅ex.
Simplifying Expression: We can simplify the expression by factoring out ex from the numerator and canceling out one ex from the numerator and denominator:f′(x)=e2xex(2x−x2).
Final Derivative: After canceling out ex, we get:f′(x)=ex2x−x2.
