%28%28x-4%29%28x-3%29%29%2F%28x-4%29
The function would be approximately the line y=x-3, BUT a point is MISSING for x=4. Now, you can find the value of y=x-3 for x=4.

Understand, x=4 is undefined for f(x) but is acceptable for y=x-3.

Limit as x approaches 4, of %28x%5E2-7x%2B12%29%2F%28x-4%29 is 1.
