tangent of f(x)=(4x)/(x+2),(2,2)

tangent of

f (x) = \frac{4 x}{x + 2}, (2, 2)

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

Solution steps

Find the slope of

f (x) = \frac{4 x}{x + 2} : \frac{df ( x )}{d x} = \frac{8}{( x + 2 ) ^{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

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

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