Graph rational equation

A. Graph the function  =
 f(x) = x-2/x^2 - 3x + 2
B. Find the domain and range of , showing all work.
C. Find the
→ , showing all work, or explain why the limit does not exist.
D. Find the
→ , showing all work, or explain why the limit does not exist.
E. Apply the definition of continuity to identify any points of discontinuity, showing all work.

The domain is just the all the x-values and the range is just the y- values

For example in the problem above:

Graph the function  =
 f(x) = x-2/x^2 - 3x + 2

Domain Range

-10 -0.27
-4 -.2
-2 -.25
-1 -.33
-1/2 -.5
0 -.66
1/2 2
1 undefined
2 0
3 1/2
4 1/3
10 1/9

Set the denominator equal to zero, and solve for X ...

Solution Summary

The domain and range are values for the polynomial equation. The domains is really all the X values. The range is all the Y values.
