F(x)= (x+2)2 f(x)=a (x-h)2+k
find : vertex, domain, range, axis of symetery , up/down, min/max , graph

f(x) = (x + 2)²    ⇒   f(x) = (x - (-2))² + 0    ⇒   h = -2 ,   k = 0

vertex:   (-2, 0)

domain:    R  

range:   <0, ∞)

axis of symetery:  x = -2

up   {a=1>0}

min:  f(-2) = 0

graph:  {f(0)=4}
