MIT grad shows how to find any limit as x approaches a finite value/constant value (and not infinity). More. Sal finds the limit of (x²+x-6)/(x-2) at x=2 by factoring and simplifying the expression. You can plug 4 into this continuous function to get 2. It happens sometimes and so we will need to be able to deal with those cases when they arise. Again, we are not going to directly compute limits in this section. Another way we could rewrite our f of x, we'll do it in blue, just to change the colors, we could rewrite f of x, this is the exact same function, f of x is casino novolino sachsenheim to x plus 3 when x does not equal 2. What is the limit of f of x as x approaches 2.
