awsedrftgy.jpgI'm not sure what to do with question 14. I don't know what it means by increasing function and I don't want you to tell me the answer but I want someone to explain it please.

When a function is increasing, what does that mean? (Think about it in relation to the gradient)
An "increasing function" is one which is increasing everywhere (just to answer the question about what "increasing" means). Also known as a "monotonically increasing function".

SeanFM's answer is good, think about what that means in terms of the gradient.
