Assignment: Working alone or with a partner, hand in a sheet similar to this one except with all spreadsheet cells showing the formulas. In excel, Ctrl ~ can be used to
show the formulas. Hand in the graphs shown (from your data) and submit the spreadsheet file in the Student_Submit\Szerminski folder. On sheet handed in provide:
Names:________________________ Filename: ex. Cyr_&_Wake.XLS
Questions:
1) What does a straight line on a rate vs. [ ]x (where x is an exponent) tell you?
2) What does a curved line on a rate vs. [ ]x (where x is an exponent) tell you?
