You can put this solution on YOUR website! x-4 / 1
a)None
b) 0
c) -4
d) 4
Think about substituting the possible values given in the multiple choices:
If we substitute x for 0, we have:
x-4 / 1
0-4 / 1
-4 / 1
-4 (this is ok)
If we substitute x for -4, we have:
x-4 / 1
-4-4 / 1
-8 / 1
-8 (this is ok)
If we substitute x for 4, we have:
x-4 / 1
4-4 / 1
0 / 1
0 (this is ok)
So, all answers are ok, which means NONE must be excluded.
