extreme f(x)=3-4x+x^2

Solution

extreme points

f (x) = 3 - 4 x + x^{2}

Solution

Minimum (2, - 1)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Plug

x = 2

into

3 - 4 x + x^{2} : - 1

Minimum (2, - 1)

Popular Examples

range of f(x)=0.5^x range

f (x) = 0. 5^{x}

inverse of f(t)=4+7t inverse

f (t) = 4 + 7 t

line (1,2),(3,4)line

(1, 2), (3, 4)

intercepts of log_{4}(x-1)+1 intercepts

lo g_{4} (x - 1) + 1

domain of f(x)= x/(sqrt(x^2-9))domain

f (x) = \frac{x}{x ^{2} - 9}
