How do you fix an MA error when attempting to graph a function? I have even tried to graph simple functions like (X) or (5) and it still says MA error.

A. This is due to a mathematical error such as

1. dividing by 0,
   
2. an illogical operation,
   
3. calculations outside the range of a function,
   
4. using the exponential function with the [^] key,
   
5. logarithm of a negative number,
   
6. calculating the factorial of numbers larger that 69,
   
7. what have you.
   
8. Check the expression of the function you are trying to graph.

1. Use keys to highlight [GRAPH] and press [EXE].
2. Make sure the screen that opens says Graph Func Y= at the top.
3. On the Y1= line enter X (use the [X,theta,T] key under the [ALPHA] key.
4. Press [F6:Draw].
5. You should see a staright line passing through the origin (0,0).
