Question

Can someone answer the attached question about Continuity for me? It seems to contradict itself.

Answer 1

a is correct, since the limit x->-7 gives 4

Answer 2

the first one is continuous everywhere since f(-7)=the limit as x->-7 of f(x)

Answer 3

a) Option two, at all x
b) At all except -7 and 3.

Answer 4

the second one is not continuous at -7 since f(-7) does not equal the limit as x->-7 of f(x)

Answer 5

what 3?

Answer 6

second function is continous at 3

Answer 7

note that is says all that apply, for question a , the 4th and last option also are true

Answer 8

oh i see
it says where function is continuous check all boxes for the second one except for x=-7

Answer 9

what i'm saying is:
the first one is continous everywhere
the second one only discontinuous at x=-7

Answer 10

I've tried every answer, but none of them work. I'm being mind-raped :/

Answer 11

did you do for the first one: B,D,F
second one: A,B
