Compute the left and right Riemann sums — 6 and 6, respectively — for () = (3 − |3 − |) on [0,6]. Compute their average value and compare it with the area under the graph of .

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
