For the intergral of -(x^2)/3 +6 interval [0,3]

Rewrite it as a function of n using the right hand endpoint without any summation sign.

can anyone help me start this problem out?

I noticed somebody else had that post before, perhaps it was you.

I am not sure exactly what you are asking, I am not familiar with the terminology you are using.

do you want the integral of -1/3(x^2) + 6 from 0 to 3?

the integral would be -1/9(x^3) + 6x + c

which when evaluated is 15

i know how to evaluate the equation but how do i rewrite it as a function of n using the right hand endpoint.

i got delta x =3/n and x*k=3k/n

what do i do next?
