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

tangent of

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

y = - 11 x - 1

Solution steps

Find the tangent point:

(- 1, 10)

Find the slope of

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

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 = - 11

Find the line with slope m=

- 11

and passing through

(- 1, 10) : y = - 11 x - 1

y = - 11 x - 1
