tangent of f(x)=2x^2+3x,(-3,9)

tangent of

f (x) = 2 x^{2} + 3 x, (- 3, 9)

y = - 9 x - 18

Solution steps

Find the slope of

f (x) = 2 x^{2} + 3 x : \frac{df ( x )}{d x} = 4 x + 3

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 = - 9

Find the line with slope m=

- 9

and passing through

(- 3, 9) : y = - 9 x - 18

y = - 9 x - 18

\frac{d}{d x} ((x^{3} - 1)^{4})

\frac{\partial}{\partial x} (11 - 4 x^{2} - y^{2})

\frac{\partial}{\partial x} (2 x^{3} y^{2} cos (6 x^{3} y))

\int \frac{7}{sec ( x ) - 1} d x

\int \frac{e ^{2 x}}{e ^{5 - x}} d x
