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 statement accurately explains whether a reflection over the y axis and a 270° counterclockwise rotation would map figure acb onto itself?

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
