Write 3 < x < 9 in interval notation.

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

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.

Drag the tiles to the correct boxes to complete the pairs. label each function. as even , odd, or neither.
