Abiologist 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 maximum number of larvae occurs when the temperature is 5°C.

Step-by-step explanation:

We are given the function ,

where x= temperature of water (in degrees) and y= number of insect larvae in water.

From the graph of the function below, we see that,

The peak or the highest point of the parabola is (5,450).

That is, when x= 5, then the value of y= 450

That is, when the temperature of the water is 5°, then the number of larvae in water is 450.

Hence, the peak of the graph means that,

The maximum number of larvae occurs when the temperature is 5°C.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
