tangent of h(x)= 7/x ,\at x=5

tangent of

h (x) = \frac{7}{x}, at x = 5

y = - \frac{7}{25} x + \frac{14}{5}

Solution steps

Find the tangent point:

(5, \frac{7}{5})

Find the slope of

h (x) = \frac{7}{x} : \frac{d h ( x )}{d x} = - \frac{7}{x ^{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{7}{25}

Find the line with slope m=

- \frac{7}{25}

and passing through

(5, \frac{7}{5}) : y = - \frac{7}{25} x + \frac{14}{5}

y = - \frac{7}{25} x + \frac{14}{5}
