Question

a) Use the Holt Blue Polynomial Regression Calculator to make a scatter diagram of these data By defaut. this will Inclucde the parabola of best fit along wilth the data points. Print out this graph, cut it to size. and paste it to your poper b) Use the Holt Blue Polynomial Regression Calculator to determine the equation of the (Round the coefficients of this quadratic function to two decimal places.) quocdraftic function of best t. c) Use your quadratic function to estimate the distance an object would fall in 4.5 seconds ) Draw the tangent ine to the parabola of best tangent line? t fit at z - 4.5 seconds. (Use a ruler) How do we interpret the slope of ths e) Use your quadratic function to estimate the velocity of a falling object after 4.5 seconds. Important Note: you will need to use software for this POw You may use the link above, or you may use your graphing calculator In elther case, will enter the data into the software and it will give you the coefficients of your quadratic function of best fit
