Question
Transcribed Image Text:Problem 9. Which of the following functions are continuous? Briefly justify
each answer.
NOTE: For this problem, I do not necessarily expect you to appeal to the
rigorous definition of continuity. You may appeal to the intuitive descriptions
of continuity given at the beginning of the lecture, as well as the facts about
continuity at the end of the lecture. (In the future, you may be expected to
answer questions about continuity more rigorously, but not here.)
a. f: R→R, f(x) = ecos,
b. f:I→R, f(x) = ecos,
c. f: R→ R², f(x) = (eª, sin x),
d. f: R→ R²,
f(x) =
[(x,x+3) if x ≥ 0,
(x,-x) if x < 0,
