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

tangent of

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

y = - 6 x + 3

Solution steps

Find the tangent point:

(1, - 3)

Find the slope of

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

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 = - 6

Find the line with slope m=

- 6

and passing through

(1, - 3) : y = - 6 x + 3

y = - 6 x + 3
