PLEASE HELP! 10 POINTS Write the equation of the function graphed. Graph of an abolute value function shifted 4 units to the left. f(x) = |x + 4| f(x) = |x| – 4 f(x) = |x – 4| f(x) = |x| + 4

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.
