Question 1049328


{{{((x-4)(x-3))/(x-4)}}}
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 {{{(x^2-7x+12)/(x-4)}}}  is  1.
