Matthieu if finding the x-intercepts of the function f(x)=x2+4x+3.His work is shown below. Which error did Matthieu make
0=x2+4x+3
0=(x+3)(x+1)
X+3=x+1
X=x-2
0=-2
There are no x

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

What is the definition of exponential decay?

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.
