extreme f(x)=x^2+4x-45

Solution

extreme points

f (x) = x^{2} + 4 x - 45

Solution

Minimum (- 2, - 49)

Solution steps

f^{'} (x) = 2 x + 4

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < \infty

Plug

x = - 2

into

x^{2} + 4 x - 45 : - 49

Minimum (- 2, - 49)

Popular Examples

intercepts of f(x)=(x-3)(x-1)^2(x+2)^3 intercepts

f (x) = (x - 3) (x - 1)^{2} (x + 2)^{3}

domain of y=x^2-5 domain

y = x^{2} - 5

line (0,2),(5,0)line

(0, 2), (5, 0)

monotone f(x)=x^2+x+2 monotone intervals

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

parallel y=-x+1/3 parallel

y = - x + \frac{1}{3}
