inflection f(x)=-x^7+7x^6

Solution

inflection points

f (x) = - x^{7} + 7 x^{6}

Solution

(5, 31250)

Solution steps

f^{''} (x) = - 42 x^{5} + 210 x^{4}

Find intervals:

Concave Upward

: - \infty < x < 0,

Concave Upward

: 0 < x < 5,

Concave Downward

: 5 < x < \infty

Plug

x = 5

into

- x^{7} + 7 x^{6} : 31250

(5, 31250)

Popular Examples

slope of y+2=-2(x-3)slope

y + 2 = - 2 (x - 3)

asymptotes of f(x)=(3x^2+1)/(x^2-2x-3)asymptotes

f (x) = \frac{3 x ^{2} + 1}{x ^{2} - 2 x - 3}

inverse of y=x^2-1,x<= 0 inverse

y = x^{2} - 1, x \leq 0

domain of f(x)=3+sqrt(16-x^2)domain

f (x) = 3 + 16 - x^{2}

domain of f(x)=(1/x)domain

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