tangent of f(x)=x^2+x,(-4,12)

tangent of

f (x) = x^{2} + x, (- 4, 12)

y = - 7 x - 16

Solution steps

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 = - 7

Find the line with slope m=

- 7

and passing through

(- 4, 12) : y = - 7 x - 16

y = - 7 x - 16

y = 2 x^{3} + 3 x^{2} - 12 x + 5

n = 1 \sum \infty e^{\frac{8}{n}} \cdot \frac{1}{n}

3 \frac{d ^{2} y}{d x ^{2}} - 21 \frac{d y}{d x} + 36 y = 5 sin (3 x)

\frac{d}{d x} (\frac{x ^{2} - 81}{x - 9})

\frac{1}{x ^{3}}
