tangent of f(x)=(14)/((1+e^{-x)),\at (0,7)}

tangent of

f (x) = \frac{14}{( 1 + e ^{- x} ) , at ( 0 , 7 )}

y = \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}})) x + \frac{14}{( 1 + e ^{- a_{0}} ) , ( 0 , 7 )} - \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}})) a_{0}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, \frac{14}{( 1 + e ^{- a_{0}} ) , ( 0 , 7 )})

Find the slope of

f (x) = \frac{14}{( 1 + e ^{- x} ) , ( 0 , 7 )} : \frac{df ( x )}{d x} = \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- x} ) ^{2}} (- e^{- x}))

Find the line with slope m=

\frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}}))

and passing through

(a_{0}, \frac{14}{( 1 + e ^{- a_{0}} ) , ( 0 , 7 )}) : y = \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}})) x + \frac{14}{( 1 + e ^{- a_{0}} ) , ( 0 , 7 )} - \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}})) a_{0}

y = \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}})) x + \frac{14}{( 1 + e ^{- a_{0}} ) , ( 0 , 7 )} - \frac{14}{, ( 0 , 7 )} (- \frac{1}{( 1 + e ^{- a_{0}} ) ^{2}} (- e^{- a_{0}})) a_{0}
