HEL lan is on a hiking trail that goes north to south . If Ian hikes miles north, elevation, in feet, can be found using the function f(x) = (x + 2) ^ 2 + 150 . Negative values would find the elevation if Ian hiked south. Find and interpret the given function values and determine an appropriate domain for the function.

the answer would be x(f)-3

Step-by-step explanation:

you already know

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.
