tangent of y=3+4x+7xe^x

tangent of

y = 3 + 4 x + 7 x e^{x}

y = (7 (e^{a_{0}} a_{0} + e^{a_{0}}) + 4) x - 7 a_{0}^{2} e^{a_{0}} + 3

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 3 + 4 a_{0} + 7 a_{0} e^{a_{0}})

Find the slope of

y = 3 + 4 x + 7 x e^{x} : \frac{d y}{d x} = 7 (e^{x} x + e^{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 = 7 (e^{a_{0}} a_{0} + e^{a_{0}}) + 4

Find the line with slope m=

7 (e^{a_{0}} a_{0} + e^{a_{0}}) + 4

and passing through

(a_{0}, 3 + 4 a_{0} + 7 a_{0} e^{a_{0}}) : y = (7 (e^{a_{0}} a_{0} + e^{a_{0}}) + 4) x - 7 a_{0}^{2} e^{a_{0}} + 3

y = (7 (e^{a_{0}} a_{0} + e^{a_{0}}) + 4) x - 7 a_{0}^{2} e^{a_{0}} + 3
