Answer:

Determine several points by substituting positive and negative values for #x#. Plot the points and draw lines through the points. The graph should have the shape of a an upside-down V.

Explanation:

#y=4-abs(x-2)#

Determine several points by substituting positive and negative values for #x#.

#x=-3,# #y=-1#
#x=-2,# #y=0#
#x=-1,# #y=1#
#x=0,# #y=2#
#x=1,# #y=3#
#x=2,# #y=4#

Plot the points and draw lines through the points. The graph should have the shape of a an upside-down V.

graph{y=4-abs(x-2) [-10, 10, -5, 5]}
