Please help, imma start crying- thanks <3

What is the lcm of 16 and 40 ? 24 and 40 ?

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.

The graph of y=x3 is transformed as shown in the graph below. which equation represents the transformed function?
