extreme f(x)=-7x^2+42x+5

Solution

extreme points

f (x) = - 7 x^{2} + 42 x + 5

Solution

Maximum (3, 68)

Solution steps

f^{'} (x) = - 14 x + 42

Find intervals:

Increasing

: - \infty < x < 3,

Decreasing

: 3 < x < \infty

Plug

x = 3

into

- 7 x^{2} + 42 x + 5 : 68

Maximum (3, 68)

Popular Examples

extreme f(x)=2x^2+2xy+y^2+2x-3 extreme points

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

extreme f(x,y)=42x^4+42y^4-4xy+19 extreme points

f (x, y) = 42 x^{4} + 42 y^{4} - 4 x y + 19

extreme y=x^2-5x-2 extreme points

y = x^{2} - 5 x - 2

extreme f(x)=x^3-(3x^2)/2 extreme points

f (x) = x^{3} - \frac{3 x ^{2}}{2}

extreme f(x)=2x-4cos(x)extreme points

f (x) = 2 x - 4 cos (x)
