What is the value of the second derivative if its convex
d²y/dx² > 0
What is the value of the second derivative if its convex
d²y/dx² > 0
What’s the value of 2nd derivative if its concave
d²y/ dx²<0
shape if d²y/dx² > 0
Convex
Shape if d²y/dx² <0
Concave
D²y/dx²< 0 at dy/dx=0
Maximum
D²y/dx² > 0 at dy/dx =0
It’s a minimum 💚
