The shape of a roller coaster is modeled by a polynomial function, r(x). describe how to find the x-intercepts of r(x) and how to construct a rough graph of r(x) so that the engineer can predict when there will be no change in the direction of the coaster. you may create a sample polynomial of degree 3 or higher to use in your explanations.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
