extreme f(x)=-3x^2-30x-21

Solution

extreme points

f (x) = - 3 x^{2} - 30 x - 21

Solution

Maximum (- 5, 54)

Solution steps

f^{'} (x) = - 6 x - 30

Find intervals:

Increasing

: - \infty < x < - 5,

Decreasing

: - 5 < x < \infty

Plug

x = - 5

into

- 3 x^{2} - 30 x - 21 : 54

Maximum (- 5, 54)

Popular Examples

extreme y=z-x extreme points

y = z - x

extreme S(r,α)=rα extreme points

S (r, α) = r α

extreme f(x,y)=5004+x^2+y^2 extreme points

f (x, y) = 5004 + x^{2} + y^{2}

extreme f(x)=2x^3-6x^2-210x+1,-6<= x<= 8 extreme points

f (x) = 2 x^{3} - 6 x^{2} - 210 x + 1, - 6 \leq x \leq 8

extreme f(x)=ln(x^2+3x+9)extreme points

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