Question

Find the removable discontinuity: d(x)=x^2-12x+20 / 3x

Answer 1

@wolfe8

Answer 2

Alright so I looked at this http://www.mathwords.com/r/removable_discontinuity.htm

And I'm thinking you just have to find where the function is undefined? I think

Answer 3

Do you know how to do that?

Answer 4

The one thing I remember is that functions are undefined if you divide by 0 so... take a look at your function.

Answer 5

What do I do with 0?

Answer 6

What values of x would make d(x) something divided by 0? Hint: a constant times 0 is 0

Answer 7

0?

Answer 8

Right. So the function should be discontinuous at x=0

Answer 9

ohhh ok, what about z(x)=x^2-7x-8 / x^3+64? the removable discontinuity is x=4?

Answer 10

I would say yes but I'm not sure.

Answer 11

Ok! Thanks for the help

Answer 12

You're welcome. Hope I did help.
