Calculus will seem easy if you have the right tutor!
What you wish to do with these values is not clear.
Is it an attempt to take the definite integral of f(t)dt over the interval [0,8] ?
If so, just calculate the area of rectangles each having base 2 and having heights given by the four LEFT ENDPOINTS found in the table. Or use the four RIGHT endpoints. Or take the average of these two calculations. All of which are crude because the Δx = 2 is so large compared to dx.

It's not a matter of THE answer, because I offered to methods and they'll likely give different answers, because these are only approximations. You did not answer my question (see my second line).
If the answer to that is yes, just follow my instructions about summing four rectangular areas. Let me know if you don't understand how to do that.
