Q:

In two or more complete sentences, define the key features of the graph below and explain how to write its equation using function notation.

Accepted Solution

A:
The graph is a function of absolute value.
 This means that for each value of f (x) there are two possible values of x.
 The absolute value function is:
 f (x) = lxl
 y = f (x) - 2 shifts the graph 2 units down.
 y = f (x + 3) moves the graph 3 units to the right.
 Finally:
 The function that best fits this graph is:
 f (x) = l-x + 3l-2
