2. find the indicated limit, if it exists. (2 points)
limit of f of x as x approaches negative 1 where f of x equals 4 minus x when x is less than negative 1, 5 when x equals negative 1, and x plus 6 when x is greater than negative 1

the limit does not exist.
3. find the indicated limit, if it exists. (2 points)
limit of f of x as x approaches 0 where f of x equals 10 x plus 2 when x is less than 0 and the absolute value of the quantity 2 minus x when x is greater than or equal to 0

the limit does not exist.
4. use graphs and tables to find the limit and identify any vertical asymptotes of limit of 1 divided by the quantity x minus 4 as x approaches 4 from the left . (2 points)
∞ ; x = -4
-∞ ; x = -4
-∞ ; x = 4
1 ; no vertical asymptotes
5.give an example of a function with both a removable and a non-removable discontinuity.
