7. Which statement about the relationship between the graph of the quadratic parent function, F(x) = x², and the function, 9(x) = -X2 + 5, is true?

What are “like terms”? why can we only add like terms?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

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.
