derivative of f(x)=-(10)/x ,\at x=-12

derivative of

f (x) = - \frac{10}{x}, at x = - 12

\frac{5}{72}

Solution steps

\frac{d}{d x} (- \frac{10}{x}) = \frac{10}{x ^{2}}

Find the value of

\frac{10}{x ^{2}}

for

x = - 12 : \frac{5}{72}

\frac{5}{72}

f (x) = x^{2} - 1

f (x) = \frac{1}{x ^{3}}

(- 1, 1)

f (x) = 9 x + 5, at x = 7

f (x) = \frac{4}{x ^{2}}
