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

tangent of

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

y = 5 x - 4

Solution steps

Find the tangent point:

(2, 6)

Find the slope of

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

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 = 5

Find the line with slope m=

5

and passing through

(2, 6) : y = 5 x - 4

y = 5 x - 4
