extreme x^3-12x^2+45x+1

extreme points

x^{3} - 12 x^{2} + 45 x + 1

Maximum (3, 55), Minimum (5, 51)

Solution steps

f^{'} (x) = 3 x^{2} - 24 x + 45

Find intervals:

Increasing

: - \infty < x < 3,

Decreasing

: 3 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = 3

into

x^{3} - 12 x^{2} + 45 x + 1 : 55

Maximum (3, 55)

Plug

x = 5

into

x^{3} - 12 x^{2} + 45 x + 1 : 51

Minimum (5, 51)

Maximum (3, 55), Minimum (5, 51)

10

f (x) = 3 x^{4} - 8 x^{3} - 6 x^{2} + 24 x - 3

f (x) = 3 x^{5} - x^{3} + 4 x - 2

F (x, y) = x^{2} + y^{2} + x + y + x y

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