Math Problem Statement
Question content area top Part 1 Devin found the equation of the parabola that fits the three points in the table to be y equals 0.345 x squared minus 0.57 x minus 2.78. Is Devin correct? Explain. x minus4 0.6 9 y 5 minus3 20 Question content area bottom Part 1 Select the correct choice below and, if necessary, fill in the answer boxes within your choice. A. Yes. Even though Devin's equation does not give the points listed in the table, that is only because Devin rounded the values of a, b, and c appropriately. B. No. This is close to the answer, but it is never acceptable to round the values in a model. Since an exact answer can be found with 3 points, Devin should have reported aequals
