The graph shows the percentage of U.S. parents willing to pay all, some, or none their child’s college education.
Use the bars that represent none, mar, and all of a college education. Represent me data for each bar as an ordered pair (x, y), where x is the percentage of college education and y is the percentage or parents willing to pay for mat percent or their child S education.
The three data points in part can be modeled by the quadratic function
Substitute each ordered pair into this function, one ordered pair at a time, and write a system of linear equations in three variables that can be used to find values for a, b. and c. It is not necessary to solve me system.
