If the original parabola defined by y = r, how would it change if y = 2(x – 3)+ I were graphed instead? a.
b.
The parabola would be vertically stretched factor 2, translated right 3 and up 1.
The parabola would be vertically compressed factor 2, translated left 3 and down 1.
The parabola would be vertically compressed factor 1, translated right 3 and down 1.
d. The parabola would be vertically stretched factor 2, translated left 3 and up 1.

Which number completes the inequality? 2/3 < _ < 7/9

The function models the number of accidents

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.
