The question is asking for a trend but you've just named a temporary increase in local minima of the graph.

#

I'm not sure if my answer will help, I suggest asking your math teacher what they mean first before turning to discord lmao

#

I think c2 would equal zero, otherwise it would follow an upwards/downwards trend

#

Well I think what you're pointing out in description isn't actually a trend

Look for the linear term. It decides the overall increase/decrease.

ebon fern I think c2 would equal zero, otherwise it would follow an upwards/downwards tren...

Lol look here

#

My answer to the question would be no

c2 does not have to be equal to zero. The graph may look without overall increase, but it can in reality be a small oncrease/decrease.

#

Only op may have the model, which contains the value of c2

#

Can we use a linear regression line?

#

Yes

#

Another way to check, mark points on maxima in the graph and see how the values of these change over time.

#

Yes, that would be correct. The observation may be confirmed by marking maxima on the graph like I said and see if the maxima increase in value over time.

You are welcome
