Consider the function and its inverse.
f(x) = x2 + 4 and f-1(x) = -
x - 4
When comparing the functions using the equations, which conclusion can be made?
The domain of f(x) is restricted to x > 0, and the domain off'(x) is restricted to x 20.
The domain of f(x) is restricted to x 20, and the domain off'(x) is restricted to x 0.
The domain of f(x) is restricted to x 50, and the domain off (x) is restricted to x 2 4.
The domain of f(x) is restricted to x s 0, and the domain of f(x) is restricted to x < 4.

Last year, a state university received 3,560 applications from boys. of those applications, 35 percent were from boys who lived in other states. part a)how many applications did the university receive from boys who lived in other states? part b)applications to the university from boys represented 40percent of all applications. how many applications did the university receive in all? i don't how to do part b so me and plz tell how you got your answer

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution

Out of 50 students surveyed, 16 have a dog. based on these results, predict how many of the 280 students in the school have a dog.
