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

Solution

tangent of

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

Solution

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

Solution steps

Find the tangent point:

(27, - 22)

Find the slope of

f (x) = - 9 x^{\frac{1}{3}} + 5 : \frac{df ( x )}{d x} = - \frac{3}{x ^{\frac{2}{3}}}

Compute the slope of

f (x) = - 9 x^{\frac{1}{3}} + 5

at

x = 27 : 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
