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 does the peak of the graph represent?
The number of larvae is greatest at 450 degrees Celsius.
The number of larvae is greatest at 5 degrees Celsius.
The least number of larvae in the water is 450.
The least number of larvae in the water is 5.

Best ResponseYou've already chosen the best response.1y = 2x^2 + 20x + 400 y = 2(x^2  10x) + 400 y = 2(x^2  10x + 25) + 400 + 50 y = 2(x  5)^2 + 450 The peak occurs at x = 5 so the answer is B.
