[tex]\frac{3}{4}x + 2 \leq x \Leftrightarrow \frac{1}{4}x \geq 2 \Leftrightarrow x \geq 8[/tex]

For any x < 8, it will return a false value.

So the formula can be true for x >= 8 cm. And that's why the smallest height in your work is 10cm, not 0 cm.

Up to which point did you measure the heights of the ball? It's bottom, middle or top?
