Sketch the graph of the function.f(x) =

3 + x if x < −1
x2 if −1 ≤ x < 1
2 − x if x ≥ 1

Use the graph to determine the values of a for which

lim xa f(x)

does not exist. (Enter your answers as a comma-separated list.)

a =

This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part.

Tutorial Exercise

Use a table of values to estimate the value of the limit. If you have a graphing device, use it to confirm your result graphically.lim x0

tan(4x)
