tangent of y=3x^2+4x,(-2,4)

tangent of

y = 3 x^{2} + 4 x, (- 2, 4)

y = - 8 x - 12

Solution steps

Find the slope of

y = 3 x^{2} + 4 x : \frac{d y}{d x} = 6 x + 4

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 = - 8

Find the line with slope m=

- 8

and passing through

(- 2, 4) : y = - 8 x - 12

y = - 8 x - 12
