Q. The number of mosquitoes in Brooklyn (in millions of mosquitoes) as a function of rainfall (in centimeters) is modeled bym(x)=−x(x−4)What is the maximum possible number of mosquitoes?million mosquitoes
Identify function type: Identify the type of function.The function m(x)=−x(x−4) is a quadratic function in the form of m(x)=ax2+bx+c, where a=−1, b=4, and c=0.
Determine axis of symmetry: Determine the axis of symmetry for the quadratic function.The axis of symmetry for a quadratic function in the form of m(x)=ax2+bx+c is given by the formula x=−2ab. For our function, a=−1 and b=4.x=−2⋅−14=−−24=2
Calculate maximum value: Calculate the maximum value of the function.The maximum value of the function occurs at the axis of symmetry. To find the maximum number of mosquitoes, we substitute x=2 into the function m(x).m(2)=−2(2−4)=−2(−2)=4
Interpret the result: Interpret the result.The maximum possible number of mosquitoes is 4 million when the rainfall is 2 centimeters.
