extreme f(x)=9-8x-4x^2

Solution

extreme points

f (x) = 9 - 8 x - 4 x^{2}

Solution

Maximum (- 1, 13)

Solution steps

f^{'} (x) = - 8 x - 8

Find intervals:

Increasing

: - \infty < x < - 1,

Decreasing

: - 1 < x < \infty

Plug

x = - 1

into

9 - 8 x - 4 x^{2} : 13

Maximum (- 1, 13)

Popular Examples

critical f(x)=-16x^2+30x+3 critical points

f (x) = - 16 x^{2} + 30 x + 3

inverse of f(x)=(x+2)^3+6 inverse

f (x) = (x + 2)^{3} + 6

critical f(x)=2x-2 critical points

f (x) = 2 x - 2

symmetry y=2x^2-8x+6 symmetry

y = 2 x^{2} - 8 x + 6
