Understanding the Concept of a Limit (Assignement)
Find the value of each expression below. f(x) = ✔ -3-12DNE f(x) = X -3-1✔ 2DNE f(x) = X -3X -12✔ DNE f(3) = X -3✔ -12X DNE
-3 2 DNE -1
Evaluate the limits, if they exist. If not, write DNE. f(x) = f(x) = ⇒ 2 f(x) =
1 2 DNE
Use the graph to determine the g(x)? 3.5 3 2 DNE
3 (B)
Evaluate each limit, if it exists. f(x) = f(x) = lim x-1=
Negative infinity Postive infinity DNE
A limit is the y-value a function approaches as you get closer and closer to a given x-value. Under which conditions would the limit as x approaches 7 not exist? Check all that apply. The graph decreases without bound as x approaches 7 from the right. The graph has a vertical asymptote at x = 7. There is a hole in the graph at x = 7. f(7) does not exist f(x) f(x)
