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

symmetry (x+2)^2-3 symmetry

(x + 2)^{2} - 3

range of sqrt(x^2-4x)range

x^{2} - 4 x

intercepts of f(x)=10x-9y=90 intercepts

f (x) = 10 x - 9 y = 90

domain of f(x)=(sqrt(x+9))/((x+3)(x-7))domain

f (x) = \frac{x + 9}{( x + 3 ) ( x - 7 )}

distance (2,2),(8,5)distance

(2, 2), (8, 5)
