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

tangent of

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

y = x + 2

Solution steps

Find the tangent point:

(1, 3)

Find the slope of

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

Find the line with slope m=

1

and passing through

(1, 3) : y = x + 2

y = x + 2
