extreme 84x-x^2

Solution

extreme points

84 x - x^{2}

Solution

Maximum (42, 1764)

Solution steps

f^{'} (x) = 84 - 2 x

Find intervals:

Increasing

: - \infty < x < 42,

Decreasing

: 42 < x < \infty

Plug

x = 42

into

84 x - x^{2} : 1764

Maximum (42, 1764)

Popular Examples

asymptotes of f(x)=(15x^2)/(x+5)asymptotes

f (x) = \frac{15 x ^{2}}{x + 5}

inverse of f(x)=sqrt(x+5)inverse

f (x) = x + 5

extreme 9sin(x)+9cos(x)extreme points

9 sin (x) + 9 cos (x)

parity f(x)=x^3-4x^2+x+6 parity

f (x) = x^{3} - 4 x^{2} + x + 6

symmetry y=x^2+6x+13 symmetry

y = x^{2} + 6 x + 13
