1. For the function gwhose graph is given, state the value, ∞, or −∞ of each quantity. If the limit
does not exist, write DNE.
Be able to state limits and/or one-sided limits for marked values on graph.
2. For a), b), and c) below use the following function
f(x) = (1
2x+ 1 if x < 4
−x+ 7 if x > 4
a) limx→4
−f(x) =, b) limx→4+f(x) =, c) Is f(x)continuous at x= 4?
For questions 3-6, evaluate the limits. If it does not exist write DNE
3. limx→4
