On a coordinate plane, two parabolas open up. The solid-line parabola goes through (negative 3, 9), has a vertex at (negative 1, 5), and goes through (1, 9). The dashed-line parabola, labeled f of x = x squared, goes through (negative 3, 9), has a vertex at (0, 0), and goes through (3, 9).

What is the equation of the translated function?

f (x) = (x - 1) 2 - 5

f (x) = (x + 1) 2 + 5

f (x) = (x - 5) 2 - 1

f (x) = (x + 5) 2 + 1
