extreme f(x)=-2x^2+4x-7

Solution

extreme points

f (x) = - 2 x^{2} + 4 x - 7

Solution

Maximum (1, - 5)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 1

into

- 2 x^{2} + 4 x - 7 : - 5

Maximum (1, - 5)

Popular Examples

range of 1/(5+e^{3x)}range

\frac{1}{5 + e ^{3 x}}

inverse of f(x)=9x+13 inverse

f (x) = 9 x + 13

inverse of f(x)=-1/2 x-2 inverse

f (x) = - \frac{1}{2} x - 2

asymptotes of f(x)=(8x^2+1)/(4x^2+2x-6)asymptotes

f (x) = \frac{8 x ^{2} + 1}{4 x ^{2} + 2 x - 6}

inverse of f(x)=-x/5+3 inverse

f (x) = - \frac{x}{5} + 3
