Is there a hole in y=4x/x^3-4x

Hello Ramirez,

I assume that you meant to put parenthesis around the entire expression for the denominator: (x^3 - 4x). 

If so, then you would have a hole wherever the denominator is zero, because it would be undefined.

So let's factor: x^3 - 4x
First factor out an x to get x(x^2 - 4).
Then, we have the difference of squares, so we can factor it to: x(x+2)(x-2)

If we set that equal to zero, there are 3 possible solutions.

0, 2, and -2

These inputs would make the denominator zero and you would have a hole on your graph.

I hope this helps,
MrEQ

Help please, id really appreciate it

Answer:

Domain: [-2, 2]

Range: [-3, 3]

Step-by-step explanation:

Domain (x) is the left and right. Range (y) is the up and down.

It's a bracket if it is included, meaning, there is no gap or hole.

If it weren't included, it'd be a parentheses instead "( )". For example, if there was an open circle.

It would go to -infinty or +infinity if it were to go on forever, and that would be in parentheses.

EX: (-∞,∞) or (-∞, 8]

You can mix and match the brackets and parentheses depending on whether or not it touches/includes the number, like I've mentioned.
