tangent of 7x^2,\at x=10

tangent

y = 140 x - 700

Solution steps

Find the tangent point:

(10, 700)

Find the slope of

y = 7 x^{2} : \frac{d y}{d x} = 14 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 = 140

Find the line with slope m=

140

and passing through

(10, 700) : y = 140 x - 700

y = 140 x - 700
