The number S of ant species in Kyle Canyon, Nevasa, can be modeled by the function S=-0.000013 E^2 + 0.042E - 21 where E is the elevation (in meters). Predict the elevation(s) at which you would expect to find 10 species of ants.
---------------------
-0.000013 E^2 + 0.042E - 21 = 10
---------------
-0.000013 E^2 + 0.042E - 31 = 0
---
Solve for E using the quadratic formula
and accepting only the positive solution.
