Re: Q4) h(x) = ax
Spent a good hour breaking my head trying to figure out where I was going wrong, finally decided to submit my best shot and can finally see what was going on!!
Thanks for the answer, somehow I was thick enough not to see what was right in front of me..

Re: Q4) h(x) = ax
Without using any calculus, I figured that that the best approximation for g bar(x) would be 0x, seeing as how the average of slopes between all combinations of two random points would end up as 0. In that case, why is the answer for the problem E for none of the above?
