tangent of f(x)=sqrt(7x+1),(9,8)

tangent of

f (x) = 7 x + 1, (9, 8)

y = \frac{7}{16} x + \frac{65}{16}

Solution steps

Find the slope of

f (x) = 7 x + 1 : \frac{df ( x )}{d x} = \frac{7}{2 7 x + 1}

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{7}{16}

Find the line with slope m=

\frac{7}{16}

and passing through

(9, 8) : y = \frac{7}{16} x + \frac{65}{16}

y = \frac{7}{16} x + \frac{65}{16}
