Apply Product Rule: To find the derivative of the function f(x)=xex, we need to apply the product rule because the function is the product of two functions, x and ex. The product rule states that if we have two functions u(x) and v(x), then the derivative of their product u(x)v(x) is given by u′(x)v(x)+u(x)v′(x).
Identify Functions: Let's identify the two functions we are working with: u(x)=x and v(x)=ex. We need to find the derivatives of both functions. The derivative of u(x) with respect to x is u′(x)=1, since the derivative of x is 1. The derivative of v(x) with respect to x is v′(x)=ex, since the derivative of v(x)=ex0 with respect to x is v(x)=ex0.
Apply Product Rule: Now we apply the product rule. We multiply the derivative of u(x) by v(x) and add the product of u(x) and the derivative of v(x). This gives us:f′(x)=u′(x)v(x)+u(x)v′(x)f′(x)=(1)(ex)+(x)(ex)
Simplify Expression: Simplify the expression to get the final derivative:f′(x)=ex+xex
