Iwould really appreciate if someone can on this problem

Arandom high school question but a hard one

G(x) = 2 sin(2x - π) + 4. using complete sentences, explain how to find the minimum value for the function.

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.
