Question

i need help with a graph problem :/

Answer 1

what do you have so far?

Answer 2

uhm well i thought it was at x=0 bcus there is a hole on the point (0,1) but I'm not sure if that is correct

Answer 3

good

Answer 4

it's not differentiable at x = 0 due to the jump discontinuity

Answer 5

where else?

Answer 6

oh so that's it? i was correct ? lol

Answer 7

uhm i don't see anywhere else

Answer 8

when you have a vertical tangent, then it's not differentiable there

Answer 9

since the slope of this tangent line is +infinity or -infinity, not really a number

Answer 10

ohh so then at x=2 also. thats right! thank u ! lol

Answer 11

correct, so x = 0 and x = 2

Answer 12

oh lol thank you ! i can't believe i didn't see it before
