Question

What are critical points?

I got this procedure guide for finding Increasing/Decreasing functions.

It said first find f'(x)

Put f'(x) = 0 and solve to get critical points.

What are critical points, I keep forgetting :(

Answer 1

see critical point of a function of a real variable is any value in the domain where either tht function is not differentiable or its derivative is zero(0)

Answer 2

see

Answer 3

@rishavraj sorry, late reply.

so if we have 2 critical points, one will not be differentiable and the other, the derivative will be 0?

Answer 4

@rational gimme 5 min, going through that

Answer 5

okiee
