Given the function f(x) = 2-4, determine the slope of the tangent line of f at x = -1 using the limit shown below. You do not have to simplify your answer.

Slope of the tangent line at x=-1

Step-by-step explanation:

Explanation:-

Given function

                            y = f(x) = e ˣ⁻⁴  ...(i)

       Differentiating equation (i) with respective to 'x' , we get
