tangent of f(x)=-6/((3x+5)^2),\at x=-1

tangent of

f (x) = - \frac{6}{( 3 x + 5 ) ^{2}}, at x = - 1

y = \frac{9}{2} x + 3

Solution steps

Find the tangent point:

(- 1, - \frac{3}{2})

Find the slope of

f (x) = - \frac{6}{( 3 x + 5 ) ^{2}} : \frac{df ( x )}{d x} = \frac{36}{( 3 x + 5 ) ^{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{9}{2}

Find the line with slope m=

\frac{9}{2}

and passing through

(- 1, - \frac{3}{2}) : y = \frac{9}{2} x + 3

y = \frac{9}{2} x + 3
