Question

Question about differentiation. on image

Answer 1

2<x

Answer 2

sorry that didnt help me at all

Answer 3

that is for sure not it,

Answer 4

if anything its not differentiable at 2, and 4

Answer 5

I think just 2

Answer 6

yes thats right. but why?

Answer 7

vertex?

Answer 8

we are looking for sharp points

Answer 9

there are two sharp points, that is when x = 2 and x = 4, but x=4 does not seem sharp enough

Answer 10

x = 4 and 2 is the answer

Answer 11

think of f(x) = |x| at x = 0

Answer 12

if you treat differentiation as slope, then it should make sense

Answer 13

ahh ok looks like 4 is sharp enough

Answer 14

so anything about that sharp will not be differentiable
