Ihave an assignment, and i have to give three reasons of why battles happen in certain areas. any ideas?

1. Military and general advantages of either side fighting 
2. The sides are fighting over THAT area the battle takes place on to rule over or own
3. Any kind of dispute occurring either toward the territory or government near the turf

b

Step-by-step explanation:x-intercepts:

factor the function

f(x)=(x+3)(x+1)

zeros at x=-3,-1

x-intercepts  --> (-3,0),(-1,0)

y-intercepts:

set x=0 in f(x)

f(0)=(0)^2+4(0)+3=3

y-intercept  --> (0,3)

find minimums and maximums

The max or min of a quadratic function occurs at x=-b/(2a). If a is negative, the max value of the function is f(-b/(2a)).  if a is positive, the minimum value of the function is f(-b/(2a)).

f(x)=ax^2+bx+c

f(x)=x^2+4x+3

here a is positive so you are looking for a minimum,

x=-b/(2a)

x=-4/(2*1)

x=-2   > plug into f(x), f(-2)=(-2)^2+4(-2)+3=-1

minimum (-2,-1)
