2. write the equation of a line that is
perpendicular to y = 3x – 2 and passes
through the point (3, 2).

What is the multiplicative rate of change of the exponential function shown on the graph?

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.

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr
