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

tangent of

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

y = - x

Solution steps

Find the tangent point:

(1, - 1)

Find the slope of

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

Find the line with slope m=

- 1

and passing through

(1, - 1) : y = - x

y = - x
