# C3 Functions curve sketching Watch

1. Dear Math genius,

I am having problems with this question
How do i find part b

Thank you for helping
2. I'm not sure what you've done. To find , you differentiate each function in their respective ranges. Also note, there is no need to write in your answers. It might be a good idea to draw out the function to get to a sense of what is happening.

I managed to do it but i want to know if there is something special about the results i am suppose to know This is becausei t is an extension exercise and thought that if i did it i will learn in depth stuff about functions

I don't think there's really much to gather from doing that question tbh other than maybe it's a continuous function between the domain values. C3 Functions isn't one of the major topics in C3 really - a lot of it is pretty straightforward.
5. "I think my answer is wrong" - well why don't you show it to us then...?
