What Is A Cassette Tape?
Materials: Graphing calculators are suggested for questions 2 and 3

Find a quadratic function that fits the set of data points and use the function to draw conclusions about future trends.

The Sony CFD-21 portable stereo system features a counter for locating certain songs on a cassette tape. When starting at the beginning of a 40 minute (on each side) cassette the counter reads 0. After 10 minutes of music, the counter reads 180 and after 25 minutes, the counter reads 422. When the tape is finished playing one side of music, the counter reads 550
-Find a function of the form T (x) = ax 2 + bx + c where T(x) represents the number of minutes that the tape has played when the counter reads 'x' (in hundreds). Use 3 of the 4 given data points in the form (counter number, minutes played) to arrive at this function. Group Strategy: Each member of the group should choose a different set of 3 points
T(x) = _____________________________
