extreme f(x)=-2x^2+8x-7

Solution

extreme points

f (x) = - 2 x^{2} + 8 x - 7

Solution

Maximum (2, 1)

Solution steps

f^{'} (x) = - 4 x + 8

Find intervals:

Increasing

: - \infty < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = 2

into

- 2 x^{2} + 8 x - 7 : 1

Maximum (2, 1)

Popular Examples

periodicity of f(x)=-3tan(pix)periodicity

f (x) = - 3 tan (π x)

critical-x^3-9x^2+14x+24 critical points

- x^{3} - 9 x^{2} + 14 x + 24

domain of f(x)=(x^2-4x-12)/(x+1)domain

f (x) = \frac{x ^{2} - 4 x - 12}{x + 1}

asymptotes of f(x)=(18x^2)/(9x^2+5)asymptotes

f (x) = \frac{18 x ^{2}}{9 x ^{2} + 5}

domain of sqrt(1+x^2)domain

1 + x^{2}
