tangent of f(x)=sqrt(x),(9,3)

tangent of

f (x) = x, (9, 3)

y = \frac{1}{6} x + \frac{3}{2}

Solution steps

Find the slope of

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

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}{6}

Find the line with slope m=

\frac{1}{6}

and passing through

(9, 3) : y = \frac{1}{6} x + \frac{3}{2}

y = \frac{1}{6} x + \frac{3}{2}
