The result displayed on Jenna's calculator is \(-1.7E-4\), which is a scientific notation for the number \(-1.7 \times 10^{-4}\).

Let's evaluate the options:

1. **0.00017**: This is \(1.7 \times 10^{-4}\), which is a positive number. This does not match \(-1.7E-4\).
2. **-1,700**: This is \(-1.7 \times 10^{3}\), which is much larger in magnitude. This does not match \(-1.7E-4\).
3. **-1.7 × 10^-4**: This is exactly the same as \(-1.7E-4\), so this matches.
4. **-0.00017**: This is also \(-1.7 \times 10^{-4}\), so this matches.
5. **1.7 × 10^-4**: This is \(1.7 \times 10^{-4}\), a positive number. This does not match \(-1.7E-4\).

From the evaluation, the equivalent numbers that align with \(-1.7E-4\) are:

- **-1.7 × 10^-4**
- **-0.00017**

These are the correct selections.
