extreme f(x)=-x^4

Solution

extreme points

f (x) = - x^{4}

Solution

Maximum (0, 0)

Solution steps

f^{'} (x) = - 4 x^{3}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

- x^{4} : 0

Maximum (0, 0)

Popular Examples

inverse of y=x^2 inverse

y = x^{2}

inverse of f(x)=3x^2+4 inverse

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

intercepts of y=x^2-6x+8 intercepts

y = x^{2} - 6 x + 8

intercepts of x^2-12 intercepts

x^{2} - 12

range of 1/(x^2-3x+2)range

\frac{1}{x ^{2} - 3 x + 2}
