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,

Answer:
x = 26.5
Step-by-step explanation:
Step 1: Write equation
(t + 10.5) + 2t + 90 = 180
Step 2: Solve for <em>t</em>
<u>Combine like terms:</u> 3t + 100.5 = 180
<u>Subtract 100.5 on both sides:</u> 3t = 79.5
<u>Divide both sides by 3:</u> t = 26.5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
<u>Substitute:</u> (26.5 + 10.5) + 2(26.5) + 90 = 180
<u>Parenthesis:</u> 37 + 56 + 90 = 180
<u>Add:</u> 180 = 180
∴ x = 26.5
