To determine when the equation \(-5 = \frac{4 - 3}{x^4 - 3x}\) is undefined, we need to analyze the denominator \(x^4 - 3x\).

The expression is undefined when the denominator equals zero:

\[ x^4 - 3x = 0 \]

We can factor out \(x\):

\[ x(x^3 - 3) = 0 \]

Setting each factor to zero gives us:

  1. \(x = 0\)
  2. \(x^3 - 3 = 0 \Rightarrow x^3 = 3 \Rightarrow x = \sqrt[3]{3}\)

Thus, the values that make the equation undefined are \(x = 0\) and \(x = \sqrt[3]{3}\).

Now, none of the provided answers \(-\frac{4}{3}\), \(-\frac{3}{4}\), \(\frac{4}{3}\), or \(\frac{3}{4}\) are equal to either of those values.

Therefore, none of the provided options directly lead to the equation being undefined, since it is undefined at \(x = 0\) and \(x = \sqrt[3]{3}\).

If I need to select only from the provided responses, they do not represent any values that cause the equation to be undefined.

whats the answer

To find out when the expression \(-5 = \frac{4 - 3}{x^4 - 3x}\) is undefined, we look at the denominator \(x^4 - 3x\).

Setting the denominator to zero:

\[ x^4 - 3x = 0 \]

Factoring out \(x\):

\[ x(x^3 - 3) = 0 \]

This gives us two conditions:

  1. \(x = 0\)
  2. \(x^3 - 3 = 0 \Rightarrow x = \sqrt[3]{3}\)

The values that make the equation undefined cannot be found directly from the provided response options \(-\frac{4}{3}\), \(-\frac{3}{4}\), \(\frac{4}{3}\), or \(\frac{3}{4}\).

However, if there is a misunderstanding and we are only checking for the responses given, the answer doesn't appear on the list.

If you were looking for a match from the list, please clarify, as none of the answers make the original equation undefined based on the calculations provided.
