1) The graph of f(x)=2x²-x on the interval [0,2] is below: 0.5 0.5 15 a) Approximate the area between f(x) and the x-axis on [0,2] using right sums with four rectangles. Draw the rectangles and show all work. b) Approximate the area between f(x) and the x-axis on [0,2] using left sums with four rectangles. Draw the rectangles and show all work. c) Find the exact value of the area using Riemann sums. Use the following limit definition for area: Area=lim f(x)Ax MIK i-1 You will need to use the following summation formulas: ² = n(n+1)(2n+1) 2-[(+¹] ind 6 d) Set up and evaluate a definite integral that represents the exact area.
2) The velocity function (in meters per second) is given for a particle moving along a line. v(t)=t²+2t-8 a) Find the displacement of the particle during the interval 1st≤6 b) Find the distance traveled by the particle during the interval 1sts6
