Draw a graph of number of undecayed nuclei to the time, for a radioactive nuclei.

Explanation

To draw a graph of the number of undecayed nuclei (N) versus time (t) for a radioactive nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Radioactive Decay**:
Radioactive decay is a random process where unstable nuclei lose energy by emitting radiation. The number of undecayed nuclei decreases over time.

2. **Identify the Initial Condition**:
