To differentiate the function ( f(x) = \frac{e^x}{e^x - 4} ) using the quotient rule, you first identify the numerator and denominator functions: ( u(x) = e^x ) and ( v(x) = e^x - 4 ). Then, apply the quotient rule formula, which states that the derivative of a quotient of two functions is equal to (\frac{u'v - uv'}{v^2}). Substituting the functions and their derivatives into the formula, we get:

[ f'(x) = \frac{(e^x)(e^x - 4) - (e^x)(e^x)}{(e^x - 4)^2} ]

[ f'(x) = \frac{(e^x)(e^x - 4 - e^x)}{(e^x - 4)^2} ]

[ f'(x) = \frac{(e^x)(-4)}{(e^x - 4)^2} ]

[ f'(x) = \frac{-4e^x}{(e^x - 4)^2} ]

So, the derivative of ( f(x) ) with respect to ( x ) using the quotient rule is ( \frac{-4e^x}{(e^x - 4)^2} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
