S (small n) =? type an expression the area

This Test: 7 pts e function given below, find a formula for the Riemann sum obtained by dividing the interval [0,3] into n equal subintervals and using the right-hand endpoint for each c . Then take a limit of this sum as n-co to calculate the area un over [0,3]. x) =4x2 a formula for a Riemann sum for the function f(x) = 4x over the interval [0,3]. an expression using n as the variable.) rea under the curve over [0,3] is square unit(s). ify your answer.)
