Are they all correct?
OpenStudy (blurbendy):
for 3, why do you say -20 is a discontinuity ?
OpenStudy (anonymous):
It should be 0, correct?
OpenStudy (anonymous):
Or 20?
OpenStudy (anonymous):
It should be 20, correct or no

x-10=10
OpenStudy (anonymous):
+10 and you get 20
OpenStudy (anonymous):
Correct?
OpenStudy (blurbendy):
it's just -10
OpenStudy (blurbendy):
-20 is not a discontinuity

in fact at x = -20, y = -41
OpenStudy (blurbendy):
for #4, -0.5 is not a discontinuity
OpenStudy (blurbendy):
for #5, (0.3) is not a discontinuity
OpenStudy (anonymous):
Thanks!
OpenStudy (anonymous):
Is that all?

for #1, (second post), 36 is not a discontinuity
for #2 (second post) -2 is not a discontinuity
OpenStudy (blurbendy):
everything else looks good
OpenStudy (anonymous):
Wait
OpenStudy (anonymous):
How is 36 not a discouninity
OpenStudy (blurbendy):
because if x = 36, then y evaluates to 144

Can you give me the indivdual answers for example 1. (9,36) Zero =0
OpenStudy (anonymous):
So I can check what I did wrong
OpenStudy (blurbendy):
you want me to evaluate x =9 and x = 36?
OpenStudy (anonymous):
I mean give the individual correct answers, for me to check what I did wrong.
OpenStudy (blurbendy):
wait, are you labeling the discontinuities as (x, y), or (x, x) ?

OpenStudy (blurbendy):

OpenStudy (anonymous):
So are they all right?
OpenStudy (blurbendy):
ill have to recheck them, so far the first one you posted is right, and the last one
