# C3 Question need help! watch

1. Q) Show that the equation ln(x+2) - x = 0 has one solution for x in the interval [1,2].

I'm not sure what type of question this is so would like some hints on how to start. Thanks

Hmm that's strange I'm not sure if I've done that topic in class yet, I'm doing AQA and I've done functions, trig, exponentials and logs, differentiation and integration by inspection but not the topic that you said, which is weird because my teacher told us to do this question??

Nope I've only been absent from one lesson so far which was differentiation. Maybe I should email my teacher.

good idea
(I think he did not see that question... Maybe you should self-teach the topic during half term)
