The roots of billy's plant grew to 3 inches beneath earth’s surface. graph all the possible depths the roots can continue to grow? (which sign) > < *> < *

If the plants are starting at -3, I would say that the plants can grow further down past negative three.

I would draw an open circle at -3, then have the arrow pointing to the left. This shows that the roots can grow lower than -3.
