extreme f(x,y)=ln(x)+y^3

extreme points

f (x, y) = ln (x) + y^{3}

None

Solution steps

Find the critical points:

None

ln (x) + y^{3}

has no critical points, therefore there are no extreme points

None

f (x) = 2 x^{3} - 33 x^{2} + 180 x + 6

f (x) = (x^{4} - 32 x^{2} - 4)

f (x) = 5 x^{3} e^{- x}, - 1 \leq x \leq 4

f (x, y) = x^{2} + 2 x + y^{2} - 8 y + 8

f (x) = x^{2} \cdot e^{x} - 2 x \cdot e^{x} + 2 e^{x}
