Question

Find the indicated limit, if it exists.

limit of f of x as x approaches negative 5 where f of x equals x plus 4 when x is less than negative 5 and f of x equals 4 minus x when x is greater than or equal to negative 5

Answer 1

if the limit exists, then you should get the same thing if you approach from the left and the right. A good way to check this on nicely behaved functions like you have here, is just tp plug -5 to both of the pieces in the function. If you get the same thing, then that is the limit, if you do not, then it does not have one.
