Which graph represents the function r(x) = |x – 2| – 1 On a coordinate plane, an absolute value graph has a vertex at (2, negative 1).

On a coordinate plane, an absolute value graph has a vertex at (negative 2, negative 1).

On a coordinate plane, an absolute value graph has a vertex at (1, negative 2).

On a coordinate plane, an absolute value graph has a vertex at (negative 1, negative 2).

On a coordinate plane, an absolute value graph has a vertex at .

Explanation:

Let , is a parent absolute value, whose vertex is located at . Then, is translated horizontally two units in the +x direction and vertically one unit in the -y direction. Hence, the vertex is located at .

Lastly, we include a graph for below.

c. bounced back and forth from worthless to worth a lot and back to worthless

answer: the time zones used to be whatever the local authority wanted them to be. one town might have 6am whenever the sun came up and another town had 6am 10 minutes later.  

the trains had a hard time when their orders said to be at a certain point at 6am.  

6am, but who's 6am.  

the railroads got together and set the time zones more or less along the longitude lines across the country.
