Question

Help please! :)

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:

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.

Answer 1

At x-intercepts, y=0. So, following this no larvae at -10 or +20 degrees celsius

Answer 2

so the third choice?

Answer 3

yes!

Answer 4

thanks :)
