Consider f(x) = - 7x2+x+1
X4+1
Which statement correctly uses limits to determine the end behavior of f(x)?
7x2 + x + 1
lim
X - to
X4+1
lim 1
so the end behavior of the function is that as x, f(x) 1.
lim
7
7x2 + x + 1
X4+1
-= lim
Elim x2, so the end behavior of the function is that as x + oo, f(x) > 0.
-= lim?
lim
X-
7x2 + x + 1
X4+1
so the end behavior of the function is that as x + f(x) 7.
7x2 + x + 1
lim
= lim
X - to
*4 + 1
7x²
so the end behavior of the function is that as x = 0, f(x)
x-100 1

Which of the following is true about the graph of f(x)=7^x. select all that apply. a= it intercepts the x axis b=it intercepts both axis c=it intercepts neither d=it intercepts the y axis

1. are the corresponding angles congruent 2. find the ratios of the corresponding sides 3. is triangle jkl congruent to triangle rst? if so what is the scale factor

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.
