= 29. In a graph of a quadratic equation (y = ax2 + bx + c), the “a” value tells us the direction of the parabola and the “c” value is related to where the parabola hits the y-axis. Use the 5 equations listed below to determine what the “b” value indicates in a graph of a quadratic equation. Y= 2x2 - 4 Y= 2x2 + 2x – 4 Y= 2x2 + 4x – 4 Y= 2x2 – 2x – 4 Y=2x2 - 4x – 4 30. The table below shows the total attendance at major league baseball games, at 10-year intervals since 1930. Use the table for the problems that follow. Round all answers to the nearest thousandth. Major League Baseball Total Attendance (y), in millions, in years since 1930 (x) Х 1930 1940 1950 1960 1970 1980 1990 2000 2010 Y a) 10.1 9.8 17.5 19.9 28.7 43.0 54.8 72.6 73.1 Which regression model (linear, exponential, or quadratic) best fits the data for interpolation purposes – predicting within the given data? Which regression model (linear exponential, or quadratic) best fits the data for extrapolation purposes – predicting outside the given data? b)
