Section 1 - Topic 5 Compositions of Functions 1. Consider f(x) = x + 3x - 70 and g(x) - 4(x-3). Part A: Find (fog)(3). ( Part B: Find g(f (3)). Bg() Part C: Find f(g(-2)). Part D: Find (g.(-2). (( 2. Given the functions f(x) = 3x and g(x) = x + 1, find [(g(x)] - [(fºg)(x)]​

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.
