Justin is on a hiking trail goes north to south. If Justin hikes x miles north, his elevation, in feet, can be found using the function f(x)=(x+2)^2+100. Negative x values would find the elevation if Justin hikes south. Find and interpret the given function values and determine an appropriate domain for the function.

Answer and Step-by-step explanation:

f(x)=(x+2)^2+100 <— vertex form of a parabola

We are trying to find the the x miles north Justin walked

—————————————————————

f(-2) =(-2+2)^2+100

f(-2) = 100 <— north since it’s not negative

—————————————————————

f(3)= (3+2)^2+100

f(3)= 125 <— north since it isn’t negative

—————————————————————

f(2.5)= (2.5+2)^2+100

f(2.5)= 120.25 <—- north since this isn’t negative

—————————————————————

Edit: I believe that all of these would be north but I might be wrong.
