Question

need precalc help will medal and fan
i will attach the question

Answer 1

Do you have a graph?

Answer 2

yes i thought i attached it let me attach it again

Answer 3

oh It just showed the question twice. No prob

Answer 4

I believe it has a nonremovable discontinuity at x = 3 since they don't meet in that point.

Answer 5

oo ok can you help me with another one

Answer 6

nonremovable discontinuties are also known as jump discontinuities. You can see it as you have to jump across x=3 to get to the second graph. Your first graph approaches 3 but goes down on the negative y-axis while your other graph approaches 3 but goes up on the negative axis

Answer 7

sure. its been a while i took precalc but ill give it a try

Answer 8

i understand what your sayinng ok let me attach it

Answer 9

wait thats two graphs

Answer 10

This graph has a removable discontinuity at x = 3. Although there's a hole in the middle of the parabola, you do have a point that can cover it up. The limit exists for that solid dot at x = 3

Answer 11

ohh i see

Answer 12

i know what discontinuity and continuity s i just dont get the dots the put in there

Answer 13

nd the removable/nonremovable thing

Answer 14

How my teacher taught that to us was we had to look at various graphs and indicate if they were removable or nonremovable. Usually nonremovable discontinuities are the infinite and jump discontinuities. Removable ones' limits exists but the nonremovable discontinuities limits does not exist

Answer 15

OH i see well thanks for the help!

Answer 16

You're welcome!
