extreme f(x)=cos(x)-3x

extreme points

f (x) = cos (x) - 3 x

None

Solution steps

Find the critical points:

None

cos (x) - 3 x

has no critical points, therefore there are no extreme points

None

f (x) = 3 x^{2} - 24 ln (x)

f (x) = 5 sin (3 x) - 5, (0, 2 π)

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

f (x) = \frac{x}{x ^{2} - x + 16}, 0 \leq x \leq 12

f (x) = \frac{x + 3}{x ^{2} - 5 x - 24}
