Question

Transcribed Image Text:Q.#9 For above function, please find and classify any other removable or non-removable discontinuities elsewhere
in the function. If non-removable, classify them as jump or infinite.
Hint: Normally one checks transition point(s) and the functions themselves. Q.#8 checked the transition
point (x= -1), so leaves only the functions themselves.
Final Answers
Function
3
1-x
for x < -1
a) f(x)=-
b) f(x) = 1
c)
for x = -1
x-2
x²-4
for x>-1
Continuous
where applies ?
(Y/N)
TOPIC 4-5: L'Hôpital's Rule
Q.#10 Using any discontinuities in Q.#8 - Q.#9, please list the intervals of continuity for f(x).
Example: If a function has removable discontinuity at x=2, its intervals of continuity are (-∞0, 2) (2, +∞0)
or, equivalently, {x|x<2 Ux>2) or {x|x=2}
Discontinuous where applies:
At x = Removable
x²-25
x+ 5-4x-x²
Q. #11 Please evaluate Lim
