A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water:

graph of y equals minus 2 times the square of x plus 20 times x plus 400

What do the x-intercepts of the graph represent?

There were 20 larvae at 0 degrees Celsius.
There were 10 larvae at 0 degrees Celsius.
The water has no larvae at −10 degrees Celsius and 20 degrees Celsius.
The water has maximum larvae at −10 degrees Celsius and 20 degrees Celsius.
