Need Help ASAP

Hey guys, I have tried doing this question, but simply cannot do it. If I can get help, it would be awesome.

question 1: The following table summarizes the calculation of the slope of a series of secants of the function y = ƒ(x). Write an expression that can be used to generalize the calculation of this average rate of change.

question 2. For the table given in question 16 above, what is the slope of the tangent approximated by these secants?

(1) Hint: $f(Q) = Q^3 + 2Q$

(2) $f\,'(2) = 14$
