Answer:

#y=256# is a horizontal line through #(0,256)#

Explanation:

The equation can also be written as #y=256#

For a function, for a specific value of #x# there must be only one answer for #y#.

#xtoy#

In this case, the value of #x# you choose has no effect on the value of #y#, which is always #256#

#5to 256, and (-3) to 256, and 80 to 256# etc

This is known as a many-to-one function because many values of #x# all give the same value for #y#.

The graph will be a horizontal line going through #(0,256)#
