Pl 1: Interpret the parabola of best fit from DA 2. This equation should have three pieces ? x2 + ?x + ? . Either ? or ? should be approximately zero and can be ignored (and you should say this explicitly). The remaining two coefficients should be interpreted based on the procedure we used to get this function: i. Does ? represent the block or the track? Why? ii. Does ? represent the block or the track? Why? iii. Does ? represent the block or the track? Why
