(a) What is the slope of the line tangent to y = x e x   a t   x   =   1 ?

(b) Write the equation of the line tangent to the graph of y  =  x e x a t   x = 1.

(a)

To determine

To calculate: The slope of a line tangent to y=xex at x=1.

Explanation of Solution

Given Information:

Equation of the curve, y=xex

Formula used:

The product rule of derivatives, for a function of form, f(x)=u(x)v(x), where, u and v are differentiable functions of x, the derivative is

f(x)=u(x)v(x)+u(x)v(x)

Calculation:

Consider the function provided,

y=xex

Use product rule and differentiate both sides with respect to x,

dydx=ddx(xex)=xddx(ex)

(b)

To determine

To calculate: The equation of a line tangent to the graph of y=xex at x=1.
