Answer 1

To determine the value that makes the equation undefined, we need to identify what would make the denominator zero in the expression given on the right side of the equation. The expression we are looking at is:

\[ 4 - \frac{3}{x^4 - 3x} \]

The term that could potentially make the expression undefined is the denominator \( x^4 - 3x \). We need to find the values of \( x \) that make this denominator equal to zero:

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

We can factor this expression:

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

This gives us two parts to solve:

1. \( x = 0 \)
2. \( x^3 - 3 = 0 \)
- Solving \( x^3 - 3 = 0 \) gives \( x^3 = 3 \), so \( x = \sqrt[3]{3} \).

To find the numerical value:

- \( \sqrt[3]{3} \approx 1.442 \)

However, the choices provided appear to be more specific numeric fractions. Therefore, we need to check these values against the equation to see which leads to a zero denominator:

1. **\(-34\)**
- \( (-34)^4 - 3(-34) \) is non-zero.

2. **\(-\frac{3}{4}\)**
- \( \left(-\frac{3}{4}\right)^4 - 3\left(-\frac{3}{4}\right) \) is non-zero.

3. **\(\frac{4}{3}\)**
- \( \left(\frac{4}{3}\right)^4 - 3\left(\frac{4}{3}\right) \) is non-zero.

4. **\(\frac{3}{4}\)**
- \( \left(\frac{3}{4}\right)^4 - 3\left(\frac{3}{4}\right) \) is non-zero.

5. **\(-\frac{4}{3}\)**
- When checking \( -\frac{4}{3} \):
- \( (-\frac{4}{3})^4 - 3(-\frac{4}{3}) \) would also not yield zero.

Given our critical points \( 0 \) and \( \sqrt[3]{3} \), we can ascertain these checks indicate none of the listed options lead to an undefined expression.

Thus, **none of these options directly yield an undefined equation based on the common interpretations**, but the direct checks don't yield any denominatory zeros from the options provided.

Please verify if there's a re-phrasing or consideration of how those options correlate with the denominator.
