Question 1037167:  hi there, I really need help :( 
 
My question is as follows:
 
sketch the graph of the given function, f(x) = x − 2 over 3. State the domain of the function, identify any intercepts and test for symmetry.
 
I really appreciate any help, thank you!

You can  put this solution on YOUR website! f(x) = (x-2) / 3 
: 
Here is the graph of the line 
: 
  
: 
The domain is all real numbers 
: 
The x intercept is 2 and the y intercept is -2/3 
: 
1) symetry about the x axis means if (a,b) is on the graph then (a,-b) is on the graph 
2) symetry about the y axis means if (a,b) is on the graph then (-a,b) is on the graph 
3) symetry about the origin means if (a,b) is on the graph then (-a,-b) is on the graph 
: 
Now we test our function 
: 
(8,2) is on our graph, since (8-2) / 3 = 2 
1) is (8,-2) on the graph, -2 = (x-2) / 3 then x = -4 
No symetry about the x axis 
: 
2) is (-8,2) on the graph, y = (-8-2) / 3 = -10/3 
No symetry about the y axis 
: 
3) is (-8,-2) on our graph 
No symetry about the origin
