Explicación paso a paso:
y = f(x) = a(x - h)² + k
vértice = (h , k)
y = f(x) = x² + 2x + 1
y = f(x) = (x + 1)²
vértice = (- 1 , 0)
Dominio
Df = x ∈ |R = x ∈ <- ∞ , +∞ >
Rango
Rf = y ∈ [- 1 , +∞ >
Eje focal
x = - 1
Tabulación
si x = -3 => y = f(-3) = (-3 + 1)² = 4
si x = -2 => y = f(-2) = (-2 + 1)² = 1
si x = -1 => y = f(-1) = (-1 + 1)² = 0
si x = 0 => y = f(0) = (0 + 1)² = 1
si x = 1 => y = f(1) = (1 + 1)² = 4
