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

Solution

extreme points

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

Solution

Maximum (1, 5)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 1

into

- x^{2} + 2 x + 4 : 5

Maximum (1, 5)

Popular Examples

domain of f(x)= x/(x^2+9)domain

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

domain of f(x)=(7a)/((a+1)(a-4))domain

f (x) = \frac{7 a}{( a + 1 ) ( a - 4 )}

domain of f(x)=sqrt(3x+27)domain

f (x) = 3 x + 27

asymptotes of f(x)=(x^2-2x-8)/(x^2+x-6)asymptotes

f (x) = \frac{x ^{2} - 2 x - 8}{x ^{2} + x - 6}

domain of (x-6)^2 domain

(x - 6)^{2}
