tangent of f(x)=(2x)/(x+1),(1,1)

tangent of

f (x) = \frac{2 x}{x + 1}, (1, 1)

y = \frac{1}{2} x + \frac{1}{2}

Solution steps

Find the slope of

f (x) = \frac{2 x}{x + 1} : \frac{df ( x )}{d x} = \frac{2}{( x + 1 ) ^{2}}

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = \frac{1}{2}

Find the line with slope m=

\frac{1}{2}

and passing through

(1, 1) : y = \frac{1}{2} x + \frac{1}{2}

y = \frac{1}{2} x + \frac{1}{2}

What is the tangent of f(x)=(2x)/(x+1),(1,1) ?
The tangent of f(x)=(2x)/(x+1),(1,1) is y= 1/2 x+1/2
