tangent of-9x^{1/3}+5,\at x=27

tangent of

- 9 x^{\frac{1}{3}} + 5, at x = 27

y = - \frac{1}{3} x - 13

Solution steps

Find the tangent point:

(27, - 22)

Find the slope of

y = - 9 x^{\frac{1}{3}} + 5 : \frac{d y}{d x} = - \frac{3}{x ^{\frac{2}{3}}}

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}{3}

Find the line with slope m=

- \frac{1}{3}

and passing through

(27, - 22) : y = - \frac{1}{3} x - 13

y = - \frac{1}{3} x - 13
