Write the equation of the function graphed.

a)f(x) = |x + 4|

b)f(x) = |x – 4|

d)f(x) = |x| + 4

d)f(x) = |x| – 4

The correct answer is:  [D]:   " f(x) = |x| – 4 " .  

{that is, the last answer choice given.}.

Note:

This graph contains the points:  " (-4, 0) " ; and " (0, 4) " .

The last answer choice given:  [D]:   " f(x) = |x| – 4 " ;  is the only answer choice containing BOTH points.
