Question

Help? Will fan and medal
When looking at a rational function, Bella and Edward have two different thoughts. Bella says that the function is defined at x = -1, x = 2, and x = 4. Edward says that the function is undefined at those x values. Describe a situation where Bella is correct, and describe a situation where Edward is correct. Is it possible for a situation to exist that they are both correct? Justify your reasoning

Answer 1

lol no its not possible for a function to be both defined and undefined at same point :)

Answer 2

a rational function is undefined when the denominator is zero
example
\[y = \frac{1}{x-3}\]
is undefined when x=3 because that makes denominator zero

Answer 3

So Edward would be correct?

Answer 4

i dont know, they dont give a specific function?

you can create 2 different functions, one where edward is right and one where bella is right

Answer 5

They don't give a specific function. I understand now thank you :)

Answer 6

yw :)
