Marine biologists are studying how water temperature affects fish populations in a specific part of the ocean. After collecting data, they found that the fish population (in thousands) can be modeled by the function:

p(x) = -2x2 + 40x - 72

where p(x) represents the fish population in thousands, and x represents the water temperature in degrees Celsius.

Which temperatures will result in no fish?

2 and 18 degrees Celsius

p(x) = -2x2 + 40x - 72

where p(x) represents the fish population in thousands, and x represents the water temperature in degrees Celsius.

What was the highest population value of the fish during the period of data collection?
