extreme x^2+8x-65

Solution

extreme points

x^{2} + 8 x - 65

Solution

Minimum (- 4, - 81)

Solution steps

f^{'} (x) = 2 x + 8

Find intervals:

Decreasing

: - \infty < x < - 4,

Increasing

: - 4 < x < \infty

Plug

x = - 4

into

x^{2} + 8 x - 65 : - 81

Minimum (- 4, - 81)

Popular Examples

perpendicular y=-7/6 x+6,(6,4)perpendicular

y = - \frac{7}{6} x + 6, (6, 4)

domain of f(x)=\sqrt[3]{-x+3}domain

midpoint (9,-2),(-1,8)midpoint

(9, - 2), (- 1, 8)

inverse of f(x)=(3-x^3)/4 inverse

f (x) = \frac{3 - x ^{3}}{4}

symmetry y=-(x-7)^2-28 symmetry

y = - (x - 7)^{2} - 28
