Which kind of function best models the data in the table? Graph the data and write an equation to model the data.

x y
0 –1
1 –2
2 –3
3 –4
4 –5

exponential; y = 3x – 1

linear; y = x – 1

quadratic; y = x2 – 1

linear; y = –x – 1

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
