tangent of f(x)=4x^2-2x+4,\at x=0

tangent of

f (x) = 4 x^{2} - 2 x + 4, at x = 0

y = - 2 x + 4

Solution steps

Find the tangent point:

(0, 4)

Find the slope of

f (x) = 4 x^{2} - 2 x + 4 : \frac{df ( x )}{d x} = 8 x - 2

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 = - 2

Find the line with slope m=

- 2

and passing through

(0, 4) : y = - 2 x + 4

y = - 2 x + 4
