F (x) = - eˣ Baseline (x - 4)<br> What​ is(are) the critical​ point(s) of​ f?
Ber [7]

Answer

given,

   f(x) = \dfrac{-e^x}{x - 4}

to find the critical point of the given expression

fist differentiating the function

f'(x) = -\dfrac{(x-4)e^x+ e^x}{(x - 4)^2}

f'(x) = \dfrac{-(x-4)e^x- e^x}{(x - 4)^2}

f'(x) = \dfrac{-e^x(x-3)}{(x - 4)^2}

now equating differential equation to zero

\dfrac{e^x(-x+3)}{(x - 4)^2}=0

e^x(-x+3)=0

now,

-x + 3 = 0            and eˣ ≠ 0

x = 3          

the critical number will be equal to x = 3

y = \dfrac{-e^3}{3 - 4}

y =e^3
