Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs. f(x)=(x-3)(x+8)

idk

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

47 - 90 = 43

43 - 180 = x

x = 137

thats not a system of equations, that is a solution
