Do you think the shape of the curve on your graph would change if you increased the half-life to 20 seconds? what does this reveal about radioactive decay?

No, the curve is constant.

Explanation:

The curve is constant. You will have an large drop at the beggining leaning into a small curve that slowly goes to zero. This is because when the concentration of the radioactive material is the greatest it begins to decay immediately and as it does, the concentration of radioactive material in the sample decreases. No mater the number, the curve stays the same.
