Evaluate dydx at x=2 for the function below.<br><br> y=6u^3+5u+2, where u=−3x^2−4x+9

bekas [8.4K]

Step-by-step explanation:

$y = 6u {}^{3} + 5u + 2$

$y = 6( - 3 {x}^{2} - 4x + 9) {}^{3} + 5( - 3 {x}^{2} - 4x + 9) + 2$

Use the chain rule.

$\frac{dy}{dx} = 6(3)( - 3 {x}^{2} - 4x + 9) {}^{2} ( - 6x - 4) + 5( - 6x - 4)$

$18( - 3 {x}^{2} - 4x + 9) {}^{2} ( - 6x - 4) + 5( - 6x - 4)$

Factor out -6x-4,

$( - 6x - 4)(18( - 3 {x}^{2} - 4x + 9) {}^{2} + 5)$

Know plug in x=-2 to evaluate the derivative

$( - 6(2) - 4)(18( - 3(2) {}^{2} - 4(2) + 9) {}^{2} + 5)$

$( - 16)(18(( - 12) - 8 + 9)) {}^{2} + 5)$

$- 16(18( - 11) {}^{2} + 5)$

$- 16(2183)$

$- 34928$

What is the vertex of g(x)=-3x^2+18x+2? a) (3,-25) b) (-3,-25) c) (3,29) d) (-3,29)

poizon [28]

C). (3, 29) would be your answer.

Explanation?:

Rewrite the equation in vertex form.

y = -3(x - 3)^2 + 29

use the vertex form, y = a(x - h)^2 + k, to determine the values of a, h, and k.

a = -3

h = 3

k = 29

The vertex = (h, k)/(3, 29)

Hope this helps!
