It  follows that

Therefore,

So

40 . B

In  every   function,   there   can be  only    one value   in  the range   (only   one y   value)  for each    value

in  the domain  (each   x   value). In  the graph   shown   in  (B),    there   are two y   values  for each    value

of  x   (that   is  greater than    −3).

41 . C

π   radians =   180 degrees

To  find    the measure of  4   radians,    you can solve   the equation     by cross   multiplying:

πx  =   720

42 . A

To  find    the value   of  n,  you can get the median  of  the numbers in  terms   of  n.  The median  is

the middle  value   in  a   set of  numbers.    Fill    the gap in  the sequence    of  numbers:

n   +   3,  n   +   7,  n   +   11, n   +   15, n   +   19, n   +   23, n   +   27, n   +   31, n   +   35

There   are nine    numbers in  the set,    so  the middle  number  is  the fifth,  which   is  n   +   19.
