Discussion Topic When we first learn arithmetic, we focus on
working with whole numbers. Then, we extend
our understanding to fractions and negative
numbers.
In algebra, we transfer these same skills to
expressions involving variables. What
elementary skills have you used so far in this
course, and how have you extended them?

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.
